There are simply not enough positive words to describe this host and this accommodation but I am going to try.
Firstly the accommodation: It is well located, beautifully decorated, very comfortable and a genuine pleasure to stay in. The four flights stairs are not onerous and should not put you off. We really enjoyed our stay and this was greatly enhanced by the kindness and generosity of the host.
We have stayed in several Airbnb properties and have generally had positive experiences with hosts being friendly and helpful. However, what we experienced here was far beyond what anyone could reasonably expect. I will not give specific examples as I do not want future renters to pressure Mark but I will say that his helpfulness and kindness enhanced our experience in NYC. I recommend that anyone heading there should stay in this lovely apartment.
