Geoffrey's place is great : very clean,very spacious, nicely decorated with everything you need, including a very comfy bed and a spacious rainfall shower.
The neighbourhood is nice, there are lots of restaurants and cafés on the avenue just around the block and the subway is close. We spent a few days in the area, we recommend Prospect Park, the Botanic Garden, and wandering around Prospect Heights to enjoy the beautiful brownstone houses.
Geoffrey was very available during our stay and answered all our emails and questions.
If you plan to spend some time in NY and want to enjoy both Manhattan and Brooklyn, Geoffrey's apartment is definitely the place to be!
