The room we selected had room for 3 with 1 full size bed and 1 twin size bed. The room was small but we literally were just there to sleep so it did just fine. The bathroom included a wall in shower and the room had a mini fridge as well. The decor was a bit much in our room but the hotel had a classic, older look to it which I liked.The front desk was always helpful and made checking in and out a breeze. Also near the door were coupons for different excursions and maps.
The hotel included free wifi and breakfast daily. The times changed depending on if it was a weekend or weekday but each day it was packed so get a table early. There is a buffet of sort to get yogurt, cereal and hot beverages. A woman also came around to take your order of their offerings; eggs, baked beans, toast. Breakfast was served quickly as they tried to accommodate as many quests as possible.
If you are looking for a quiet hotel that is not in the heart of London, I do recommend Saba Hotel. The walk to the tube was easy but we also made the 20 or so minute walk to the Kensington area from there which was also a breeze.
