The place is wonderful, very clean, and located in a beautiful area. Very close to the Goodge street tube station, and a walking distance to restaurants and shops!
The aptm is amazing, new furniture, large living room with brand new kitchen.
Heater system perfectly working, so the place was warm and cosy.
What could be improved is the communication: the aptm is managed by a company, all the information about the aptm are in a book in the living room and if you need something else, they don't know how to help you (i.e. they never replied to my question on how lock me in when inside - nobody can enter without a key, but I just wanted to know for extra safety).
Also it is not really convenient to collect and return the keys, in a 8 min walking distance place (when cold or raining, with luggage).
I would anyway come back anytime since the place is one of the best I've seen in London! Highly recommended when in town!
