Peri was very quick to respond to my booking request and met me in person outside the flat. This place was very clean and beautifully decorated, the plants in particular were a lovely touch and made the space feel very welcoming. The bed was very comfortable and the bath/shower were really good. Location is great, only a 15 minute walk to a really nice part of Hampstead Heath and close to shops, restaurants, historic sites of interest and the tube. Peri herself was quick at responding quickly to any queries by whatsapp. Unfortunately we had a few issues, such as me being given the wrong keys so I ended up locked out of the flat for a short while, and problems with the main lights which flickered, however Peri did her best to resolve both problems quickly.
One thing to bear in mind is that the flat could feel quite noisy at times. As the building is home to several flats expect to hear people going in and out with a hard to open front door, and a pianist upstairs whose playing is (not unpleasantly) audible. I also found the flat's fridge to be quite loud at night.
Overall a nice stay in a good area.
