I would highly recommend a stay at Althea's during your New York and Brooklyn visit. The hospitality was great and she was easy to get hold of if we had any questions.
The apartment is a good size, the two double bedrooms are very spacious. We had a cot bed for our toddler in one room and there was still enough space to manoeuvre around the room. The living room and dining area is cosy and was a little cramped for four adults and a toddler. There aren't any windows in this area of the house which during the late autumn, makes it quite dark. When sat at the head of the dining table facing the wall, the house is noticeably on a tilt.
It can get warm as you are on the top floor but we asked the host to turn down the heat on the first night we stayed which she did. There are vents where you can lower the heat but if you turn it down too much, the temperature drops quickly.
The bathroom is a decent size and the shower head is powerful which is great.
The location is ideal - few minutes walk to the subway and the area felt safe to go out in the evenings and return using the subway. There are amenities nearby if you would like to buy groceries or get coffee.
There are quite a few stairs which is to be expected with the style of house. Minor difficulty getting the suitcases up and down the stairs on arrival and departure but we managed.
