A few more thoughts on this hotel.
Pro
Location was perfect for our needs.
This hotel is relatively inexpensive for the area - especially with nearby Parliament not sitting. Try two nights on points for less than one at the Marriott.
Upgraded to Junior Suite well in advance of arrival without asking or applying NUA.
All staff seem friendly and welcoming. Check-in interaction was very good, although I asked if room included requested shower instead of tub. He assured me it had both; it didn't, but we elected not to move despite tub-only.
Welcome gift - first at a Renaissance in many years - was a contributing factor to not requesting room change. They obviously thought initially only one person was staying as 2 more beers for my wife arrived at the door within minutes (without asking).
The bed was very comfortable.
Liked the walk-in storage area with closet and luggage bench. More hotels should do this.
Breakfast in the restaurant is very good - probably the best a week into this trip. Both selection and quality were excellent, from the warm full-size pain-au-chocolat to the ham carving station. File that under "unexpected". We were seated in the library-like Members lounge to the rear of the restaurant - not to be confused with the M Club. (The sign "Elite members only" was clearly visible - another surprising touch.)
Food and beverages in the bar are reasonable for the area.
Cons
Lounge observations in Post #18 above. At least there is one and it was (sort of) open.
The bathroom in our suite was tiny - think cruise ship size, with most of it taken up by the bathtub. It was the smallest I've seen at a hotel that didn't have Moxy in the name.
The TV is in an awkward location: easy to knock when going to or from the bathroom and hard to watch from bed. Very much like recent TownePlace Suites design with less pivot. On the surface there appeared to be a lot of channels but as many as 50% were blank or did not contain correct content.
Neutral
The design and decoration of public areas is an acquired taste. We didn't mind it, although the black walls near the elevators could use some paint touch-ups.
The bright green parakeets attended in great numbers every afternoon. (Google them.) They generate a fair bit of noise outside the window/Juliette balcony but are entertaining to watch as they dart in and out of recesses in the walls and the trees in front of the Marriott Apartments behind.
