Treasure's place in Brooklyn is as described. It is spacious and is well stocked. We found the neighbourhood it is located in to be very safe and the neighbours very friendly. There aren't a lot of walkable restaurants in the area but there are lots within a subway stop or two ( 20 - 30 ish minutes if you choose to walk.
If you are using it as a home base for Manhattan, it is only a 5 minute walk to the L or M subway and then a 15 minute subway ride to downtown Manhattan and it is a restful place away from the busyness of Manhattan.
The reason I gave it a three is because, when I booked it had AC listed ( it doesn't it has fans). We were there for an extremely hot period and the first night it was like a sauna. Although Treasure tried to find fans they were sold out so although the heat wave broke a little, it was still a little warm for us. Also the person upstairs on several nights was walking around very late at night - actually early in the morning. This was not an issue for sound sleepers in our party but was for light sleepers.
Treasure himself was a lovely host. He was prompt on all questions asked and extremely helpful in providing information and making us feel welcome.
