Pros:
Living area bright light. Comfortable seating. Well-equipped kitchen. A/C heat/cool worked very well. Plenty of towels, maid service mid-stay. Back bedroom totally quiet. Good bathrooms. Very firm mattresses (too firm for some of us). Bob was easy to communicate with.
Best of all, easy, lovely walks to many sights, beautiful parks and buildings, nearby grocery and tube stop around the corner. Many, many excellent restaurants with various cuisines in the immediate neighborhood. Easy to get a taxi.
Cons:
Hefty fee for late arrivals (coming from US you are either hours too early or late). Convection stove worked erratically, despite one of us couples having one at home. Sole coffee maker uses pods that were hard to obtain, though Bob supplied more the next afternoon. The front bedroom got a lot of noise from street construction, the third bedroom, and especially the bathroom, are smaller than the others, and the combo washer dryer does not get the clothes dry, even with a very very small load. There is a drying rack.
