Check In

Check in was easy and fast.  They explained where the breakfast was as well as the pools and gym.  No issues.

Room

Booked a basic room and used a DSU and got a Grand Executive Suite with Acropolis view.  The room was nice and had 2 balconies, both of which you could get a decent view of the Acropolis from.  You also got a great view of the very busy street down below, which is a major thoroughfare in Athens, as well as the numerous sex clubs and shops in the area.  

The room was large enough but honestly beyond that was not anything special.  It had a separate area which could be closed off from the bedroom with couch and chairs, as well as a table and second bathroom.  A very nice room, but as mid/upper level suites go, it was just fine.  

The shower was a good size rain shower, which was nice, although it was one of the style with an open entry and no door, which of course, gets water everywhere.  

The bed was comfortable enough, although the thermostat in the bedroom did not seem to work on auto, so you had to either leave it off and the room got hot, or turn it on manually, which eventually got it too cold.  

The road noise from the highway is significant here.  I mean, I slept fine, but it is plenty loud, at least from the 4th floor, so if that is an issue for you you might not want a room on that side.  

Service

The service here was honestly pretty bad and was one of the biggest failings.  The first day they did not replenish the water bottles they provided, and I had to call down to get some water.  After some discussion on the line, they said they would send some up and the maid who brought them up was VISIBLY irritated at having to do that.  

The second day, the housekeeping had not serviced the room when we returned at 1345 hours.  I mean, I know they have "until 1700" technically, but when you are offering 2 servicings a day, are you seriously going to service it at 5pm and then at 8?  We then took a nap and at some point between about 2-5 they tried to service it and left a card. 

We went to dinner and when we returned, they had serviced it but failed to replace a few towels or the water again. I went down stairs to talk to the desk about if they could send up water and replenish the missing towels.  The gentleman at the desk was pleasant but tried to tell me the water was once per stay, and I had to show him the Glob terms, which irritated me.  I hate having to educate you on the benefits, just provide them.  We went to the bar and had a drink and upon returning we saw the same housekeeper in the hallway who gave us a very nasty look after taking the cart from our room.

The next day, we returned at around 6pm after leaving at 0730 and it was not cleaned yet again.  My wife wanted to get a snack from the little informal "club" area, which is just an area in the back of the lobby which is kind of blocked off.  I passed by the desk and asked them to clean the room again, and I guess I was talking to the desk manager who apologized.  

We went to the little club area, and sat down and grabbed a few mediocre food items, and the waiter never once asked if we wanted a drink.  Passed by several times, but never asked, and I even tried to flag him down once or twice, but to no avail.  

Overall, no one was ever rude or anything (although the housekeeping lady was pretty visibly pissed off), but the service just was not up to snuff at a Grand Hyatt.

Dining

Breakfast here was very good.  The buffet was excellent, with a large variety of excellent local pastries, fruits, yogurts, cheeses, meats, hot western items, and fresh juices.  Very good and one of those buffets where I ate way more than I should have every morning.  An excellent value for Globs, and I believe it was 32 euro if you were paying.  I did not dine in the restaurant otherwise.

Location

The location here is, as most have mentioned, pretty substandard.  It also is not as bad as many make it out to be.  The area itself is just fine, although it is filled with sex clubs and strip joints, but honestly, you see a lot of those all over Athens.  It did not feel dangerous or anything.  

As for the main sights, it is about a 25-30 minute walk to the main sights of Athens for tourists, and it is a straight and easy walk.  A cab is the only real other option (the Metro is about a 15 minute walk away and we never used it).  The main issue with cabs is that honestly, while it should be easy to get a cab to the center in about 5 minutes for about 5 euro, 95% of the cabs in Athens are out to screw you and cheat you in every possible way and it gets tiresome.  There were honestly a couple of times we did not leave the hotel when we kind of wanted to because we did not feel like walking and did not feel like dealing with cab nonsense.  Having to always be demanding the meter be turned on, checking the money you give, watching out for BS added surcharges, incorrect fares, etc gets old, and since it is pretty requisite to being able to stay here, it has an impact.  Sure you can walk once or twice, and while it is not hard, like I said, it is a solid 25-30 minutes.  Maybe 20 if you walk fast.  

Overall

I paid 110 euro a night out the door and given the room I received and the breakfast quality, overall I was happy with it.  That being said, without a significant room upgrade using a Globalist upgrade instrument and free breakfast, I would be a lot less happy here.  The hotel was fine, but was not great and the polish was certainly not there.  The location was not horrible as said, but was a definite detractor overall.  There is a reason the rates are so cheap.  Would I return?  As a Glob at that price...probably.  I would definitely look closely at other options first though regardless.  As a non Glob?  No way.
