The apartment is in very good condition with a newly renovated bathroom and kitchen, and new furniture. The hosts were quick to respond and seems like nice people.
The problem is the sofa bed and the noice. The sofa bed is awful to sleep in. The back of the sofa folds down so that the “bed” is even but there is no additional mattress. You basically sleep on the sofa cushions, which mens that the “bed” is uneven and way to thin for allow a good nights sleep. So, the apartment sleeps 3, not 4 people.
The other problem is the noice from the metro on the Williamsburg bridge. The apartment is on the third floor which sets it just 25 yards from the bridge and on the same hight. Since the bridge is old, the sound when the metro goes by is quite deafening. The windows fronting the bridge have double glazing which takes away a lot of the noice, but the windows facing away from the bridge does not. We slept with earbuds but woke up several times every night. We have stayed in big cities before and know that there are always some noise but this was something else completely. However, if a mattress is provided and the windows fixed with double glazing this will be a very nice apartment.
