Marie's place is in a great location and is a good-sized one bedroom for NY. Not fancy but totally adequate and clean with a comfortable couch and bed and full bathroom and kitchen.
The building seems safe. It is an older building, which means the walls are thick - I could hear doors opening closing in the hallway but didn't hear neighbors' voices, which was great. It also means the hallways aren't air-conditioned but you're not in them very long bc the elevator comes quickly and the unit is close to elevator.
Marie greeted me personally and was very responsive to questions.
