Boris was on a trip when we visited, but was easily reachable through e-mails. Additionally, he helped us get in touch with his nephew (who was also very helpful), who lives in the same building and granted us access to the apartment. The apartment itself is nice and comfortable. There are two bonuses: the subway station is close by, and his 2 cats are very sweet! We ended up leaving a day early (though really just a few hours, and not because of any issues with the apartment), and we hope to get a chance to meet Boris the next time we are in NYC!
