We had a wonderful stay at Rosie's place in Park Slope.
Communication was great from the start; she contacted us early to check on how many guests we were bringing, who wanted to share rooms, etc. to make sure that the space was configured properly for us.
The space itself was perfect. We had 5 people and 2 small dogs with us, and we fit comfortably. If we had 2 more it might have felt a little tighter, but none of us were couples either so we all preferred our own personal space. The place was extremely clean and well-appointed, and Rosie took our dirty dishes each afternoon to clean for us (the kitchenettes don't have sinks, which was no big deal for us). She also swapped out bath rugs for us partway through (we'd gotten them dirty thanks to all of the dirty slush after it snowed).
There were a lot of great touches, including various teas and coffee (regular and decaf), whichever milk we preferred for coffee creamer, and a few selections of beer and wine. Rosie also bought us some cute 2018 eyeglasses and noisemakers for New Years (we stayed over NYE), which were really fun and very thoughtful of her.
At the end of our trip one of my brothers had to stay an extra day for a last-minute job interview, and Rosie was able to accommodate him with no issues, which was awesome. She was also very flexible with check-out time, since she didn't have any tenants right after us and the weather was terrible (my brother checked out on the day they got hit by the storm, so he had to shovel his way out lol).
All in all, a fantastic stay, and I would come back in a heartbeat!
