I really loved my stay in Belsize Park. I moved to London so stayed for over a month while I secured a place. I was able to put away clothes in the closet and wardrobe and had space for everything. Basically, I made it my own. The living space is super functional with a comfortable murphy bed that you put away and forget about all day and great wifi (I work remotely and it was perfect). I was able to do my laundry and they even have a clothes rack to dry clothes on which is perfect. The kitchen has what you need for simple meals and the shower and bathroom are fine. Overall, I could live in a space like this.
The Belsize Park Tube is super close and there are 3 grocery stores, a Starbucks, a Costa and several restaurants around. You can walk to Camden Market in about 25 minutes or take the Tube. I've loved my stay.
Alev is a super host and was flexible about checkin and always available rather quickly to answer questions.
