Apartment - We loved our stay. as a tourist family (from UK) with a 4 year old and 18 month old. A well stocked kitchen, comfortable beds, comfortable furniture, 3 toy boxes and a big TV. A great space and good value for the space. We got a good sleep as the gbed is comfy and we didn't hear much noise from the sleep (we had the aircon on).
Location - less than 5 mins walk to L train, 10 mins to J Train and I think you could also walk to the G train. There's grocery stores, pharmacies, barbers, restaurants etc all within a couple of blocks. Maybe 15-20 mins from front door to 14th street Manhattan.
Neighbourhood - it's a friendly, diverse and majority hispanic neighbourhood in East Williamsburg. The area is safe and has a nice balance between gentrification and authenticity...it's not too fancy (yet!). There are some really good and friendly neighbourhood bars. There would be some more desireable parts of Brooklyn and of course Manahattan, and whilst we didn't instantly love the neighbourhood, we definitley really enjoyed it.
Host - Jason and his Dad were perfect and gave us all the information we needed and responded kindly to any of our questions or requests...that made a massive difference to our stay.
Overall - glad we decided to stay here and it was decent value. A good option for us in terms of space, facilities, value and location.
