I have stayed with Jaclyn & Mattie before and it's one of my preferred places to stay in Williamsburg. The location is perfect (right off Bedford) and the place itself is clean and quiet and has a good vibe. This was my second stay with them and as soon as I booked my NYC trip theirs was the first place I looked up.
Jaclyn & Mattie are professional AirBNB hosts and it shows. Everything in the process is streamlined.
The place itself is cleaner than what most hosts offer in this price bracket. They have professional cleaners come after every guest leaves to tidy up the room and the apartment and change the sheets, towels, etc.
The apartment itself is relatively quiet with high ceilings and a perfect retreat from the city -- and the location is ideal. Right off Bedford Ave (which is the main strip) in the coolest neighborhood in NYC.
Highly recommended.
