A lot to recommend: Spacious studio, immaculately clean, well-stocked especially if you want to cook a bit. Very quiet (at least my unit). Self check-in worked perfectly, security was good, wifi worked great. Good price for value since out of tourist zone but still walkable to many sights as well as shops and restaurants. 3 nearest Tube stations are all 1/2 mile away but there is bus service right outside.
2 warnings: Other reviewers are not kidding that the "double" bed is both small side-to-side and VERY short in length. I'm average height for a woman and my toes hung off the bed! Someone taller would have to sleep diagonally. I can't imagine 2 adults sharing this bed.
The second warning is that even if you use the lift the building is advertised to have, once inside you will always have to walk up at least 8 steps (in addition to 3 steps outside) because the lift is situated between floors. I had to walk up 16 steps to the 2nd floor. If you can't do stairs, DO NOT stay here!
