I stayed in Bobbi's place for 10 nights in December.
Location-wise, there is a nearby bus stop that goes to Brooklyn Downtown, and the nearest subway is a 10-minute walk (from there about 30-40 minutes to get to Manhattan). The area is safe even though it may look a bit shady, I was never bothered coming back (up to 11pm ish) walking from the subway station.
Wi-fi works great and hot water also works all the time (except for the 2 days when there was a cold wave and the pipe froze). However the portable heater inside the room is warm enough.
I didn't get to meet Bobbi, but she was always helpful and responsive.
Some (minor) downsides:
- room was a bit dirty, I could notice some debris on the carpet
- the bed was like a sofa bed, there was some hard metal in the middle which might be uncomfortable for some
- window in the room could not be opened
- kitchen area was a bit messy and dirty -> I didn't cook so I was fine
Overall it's a great value for money.
