Dani is a kind host and was helpful with questions as well as with convenient check-in & check-out. The flat is everything you could ask for when in London for a couple of days. The neighbourhood is great, Hampstead is Hampstead. Shops and the tube round the corner. Although the road is busy, it isn't too noisy and sleeping next to the street still possible.
We stayed two nights as a couple and would recommend the flat for solos or couples.
