My parents stayed at Stevyn's flat for around 2 weeks. They had a great time and enjoyed the flat very much. It is clean, cozy and equipped with everything you needed to feel at home. On top of this, the views from the 9th floor makes it even more enjoyable.
The building is clean, tidy and quiet, which adds to the positive experience.
The location is fantastic, close enough to the centre of London (there's a bus that takes you to Archway station in 5 minutes) but in the middle of a beautiful residential area surrounded with parks, shops and restaurants (Crouch End).
Communication with Stevyn was great. He was always available to answer my questions and he even showed me the flat in advance, to let me know how everything worked.
I will recommend this flat to anyone who would like to visit London and experience it as locals do.
