The appartment of Deirdre was clean, comfortable and in an intresting neighbourhood. Right around the corner there is a laundry, right beside that a nice cafe to hang around during the laundry. To explore Brooklyn it is a good place to stay. Also to got to the city it is easy to get there.
Concerning the check in and out - it is easy once you get to the appartment. For me it worked out well, following the instructions. I didn't need any further help, but Deirdre was in touch via mail/mobile for any cases.
