We really enjoyed our stay at Marc's place! It was clean, comfortable, and beautifully-decorated. The wifi worked well no problems streaming media) and was easy to connect to. The air conditioning was great during a heat wave! The temperature was always comfortable.
Marc made us feel welcome and his communication was fantastic: he had printed and laminated instructions for us, and he responded almost instantly to any messages we sent.
The location of the apartment was great: very close to two subways stations, right across the street from Prospect Park, and lots of amenities nearby (grocery stores, cafes, bars, etc.)
The only downside was lots of noise, both from the air conditioning unit and from trains nearby. There was also a bit of noise from the building buzzers and people coming in and out, although the building was otherwise very quiet. It didn't disturb us much, but would be uncomfortable for anyone with sensitivity to noise!
