I stayed here for a long weekend in the winter. The private room is small but warm and comfortable and the common space (includes a small kitchen!) is clean and cozy. Thiago was responsive prior to my visit and especially so as I was coordinating my arrival on the day of. There's both a key to the private room as well as to the building and the apartment, which is great for peace of mind. I would recommend staying here, particularly if you need MTA access to anywhere on the Upper West Side.
