We loved staying in Aron’s flat. It is spacious, clean and comfortable (great beds!). The area is a bit rougher than other parts of Brooklyn, but we still felt very safe there with our daughters. It is very close to an underground station. The house is very spacious, the flat definitely big enough for 4 people. Other than that, the house is old and therefore quite noisy. You can sometimes hear people on the stairs and in the other flats.
Aron responds quickly to messages and was very relaxed, also we were allowed to check out a bit later due to our flight.
All in all, a very nice stay!
