(Note: I have now consolidated several posts I made over the course of a stay into this single report.)

I don't know that I'm the first to stay here, but it appears I'll be the first to report. . .

This is a beautiful property. There is no indication, whether facility or service, that it just recently opened. They are on top of their game.

Service is first rate -- professional yet warm and very helpful. My bags did not make it to IST and the concierge team worked it as aggressively as possible, providing me updates as they had contact with the airline service company (which was pathetic, so it was nice to have someone local working it for me).

As a Diamond member, I was upgraded from a Deluxe King to a Spa Room. (I'm told that Diamond members will be upgraded one room class, so be sure to reserve Deluxe King, as opposed to Standard Queen if you want to the chance to experience one of these rooms.) This room is aptly named, as literally half of it is the bathroom.

The bedroom portion is exactly the room shown on the hotel's home page. It is state-of-the-art, with everything electronic that you can imagine. (Lights and blinds electronically-controlled from bedside, AV inputs on the desk for the plasma screen. . . ) The bed is fabulous, if a bit firm for my taste, with great linens and exceptional pillows. Hard wood floor, with Turkish rug and very comfortable and functional furniture.

The spa and bathroom in the Spa Room is extraordinary. All heated tile floors. Two sinks (one with drinking water) out front at the vanity, with doors leading into the WC on the right and the spa on the left. In the spa is a soaking tub (with remote controllable light therapy option or in-wall TV), an area for an available in-room Turkish scrub if you're so inclined, a personal steam room and a spacious rain shower area -- all in the privacy of your own room. Bath products are Blaise Mautin, with more options provided than you can imagine.

A nice plate of fresh fruit along with a note from the Guest Services Manager was in the room upon arrival. (I don't know if it was a Diamond Amenity, as the note did not mention status.)

As a Diamond member, you receive complimentary breakfast in the lobby breakfast, which includes the entire breakfast menu, with many cook-to-order options, in addition to an extensive buffet spread. The breakfast is truly excellent.

Had room service dinner the evening of arrival. It which was first-rate. Nice variety, reasonable prices (relatively speaking for a hotel of this level), promptly delivered and exceptional service.

The spa and workout facility is open and very nice. Signature Massage for 60 minutes is ~US $130, same for a 60 min. facial. Turkish Scrub is ~ $100. The workout room is not particularly big, but certainly adequate for a hotel of less than 100 rooms (unless there happens to be an exercise convention in-house, I suppose). Most equipment one would need is available. The Signature Massage was a little light, but enjoyable. I would recommend a custom-designed one if you're looking for deeper, therapeutic work.

Concierge: This was the one downside for me. While every concierge was very friendly and helpful (particularly, as I noted above, when it came to my baggage), I had a bad experience that was key. I was specifically interested in a restaurant that had received rave reviews in the New York Times (1897 Konyali). In helping me to book a reservation, the Concierge found it was closed on the night I could go. He insisted that there was a sister restaurant, part of the same Konyali chain of three restaurants, with the identical menu. I was skeptical, given what I had read in the review, which discussed more contemporary twists on traditional Turkish dishes, but he was insistent. So I decided we would go there. The next day, I confirmed with another concierge that, in fact, the menu was the same between the two restaurants and she confirmed that it was. Well, it was not. Not by a long shot. The menu was very traditional Turkish cuisine, which I was not interested in, as it was essentially a repeat of the night before. The meal was an enormous disappointment. I should have followed my gut and done more independent research, but with such insistence from each concierge, I trusted their knowledge. I should not have.

The neighborhood is in a very luxurious area, with first-rate shopping and dining all around. It was about a 40 minute taxi drive from the airport (approx. US $25), about a $10 ride to the main tourist areas in the old town area.

WARNING: Getting to this hotel can be a problem: Over the course of our stay, not a single taxi driver had any idea of this hotel or its location. Without fail, every one wanted to take us to the Hyatt Regency (which, fortunately, isn't too far away). A helpful member of the staff created a description of the hotel's location, written in Turkish, for me to hand the taxi drivers when we got in. That worked well. Only one time did a driver look at the document, we had the conversation about this being the new Hyatt hotel -- the Park Hyatt, and he still took us to the HR.

If anyone would like me to e-mail this document, I'm happy to do so. Officially, the hotel doesn't have anything this helpful, so if you're going within the next few months, I think you'll find it helpful, so just send me a PM and I'll fire it off to you via e-mail.

All things considered, this is an excellent property in every important way. In particular, the staff was so nice and helpful, providing the ideal balance between highly professional and yet very warm, friendly and willing to help with anything. I cannot overstate how impressed I was by the people. This is one of the finest hotels and hotel rooms I've ever experienced and I highly recommend it.
