Stayed at the Envoy Hotel down in Seaport this week. A few thoughts:

I didn't have a lot of time to explore the hotel and the amenities, as work, clients, dinners, etc. kept me pretty busy.

I was upgraded to a "deluxe" water-facing room as a Gold, which was more than expected since the hotel was showing sold-out this week. Room was decently large, though some said the center-placed bed is a little weird. Offered a $12 breakfast voucher each day, or 750 points in lieu of breakfast. I chose the points since my breakfasts were already planned with my colleagues so unfortunately no review on the breakfast.

Bathroom has frosted glass as partitions, and does have a closing frosted/patterned glass door that slides closed. However a note for those who are more than one: the bathroom has limited privacy since the frosted/patterned portion of the glass doesn't really enclose the bathroom floor-to-ceiling... you could easily get a peek if you peeked over or under. Bath amenities were by "fresh" and were actually pretty nice, and seemed to be real sample-sized amenities (as in they had barcodes on them) rather than the standard "distributed by Sysco/Marietta/La Bottega" stuff.

Additionally, the "water view" room was really just a view of the Barking Crab restaurant (I was on the 4th floor) and the bridge from downtown Boston... so if you are standing without pants on in the window, everyone crossing the bridge can most likely see you.

Room was generally nice, and there were power outlets/USB outlets EVERYWHERE, which I appreciated. Much more boutique-feel than your standard Marriott -family hotels, which I appreciated. Two bottles (full size at 16.9 oz) of Envoy-branded spring water were provided each day, which was nice. I noticed the room did not have any facilities for making coffee/tea, or a mini-fridge. These may be a deal-breaker for some, though I'm sure you could call down and ask for those, but just an extra inconvenience when it doesn't already come standard.

Unfortunately the biggest dealbreaker for me (and the reason I would not return): the air conditioning unit in my room was EXTREMELY noisy. It also doesn't regulate the temperature of the room very well. Instead of keeping the room at a constant temperature, it's one of those which will turn on very cold (and loud) for 5 minutes, shut off for 5 minutes as the room warms back up, and turn back on for 5 minutes. So it's a consistent on/off (even if you change the thermostat settings) which can feel quite disruptive.

The Envoy was not cheap (though I suppose that goes without saying in Boston) -- $400 a night including taxes on a corporate rate, which is pretty much the same as the Ritz (on our corporate rate) and the Renaissance nearby. Besides the A/C issue, the hotel was generally nice (and only a 5 minute walk to my office), but I will probably not returning if I cannot sleep at all Will probably try the Ritz, Langham, or Kimpton Nine Zero next time, though my colleagues also mentioned that Ritz is quite underwhelming.
