My cousin and I stayed here for a week and it was great. Marta was a wonderful host and even turned the heater on before I arrived to make sure it wasn’t too cold. She was also really responsive when we had questions.
The location was close to three tube stops (all walkable within 10-12 minutes), so it was really convenient.
There are three flights of stairs and no lift so be prepared to work out the first day you arrive with your luggage, when you leave, and just on the daily.
The neighbors were loud one night, but Marta immediately let us know she would talk to the landlord and all the subsequent nights were very very quiet.
I would definitely stay here again. Thanks, Marta!
