Alex replied quickly and very politely to my questions before my stay. Our interactions while I was at the apartment were limited, though he was always polite. The apartment is very clean, the bed one of the most comfortable I've ever used, and the bedroom lighting is adequate for reading. The street was noisy, with drilling until midnight one night, but I had earplugs, which helped. The location is excellent--walking distance from Grand Central Station, the subway, Central Park, several museums.
