The good:
Very near to subway Q line which conveniently goes to Manhattan (ca. 35 min).
The neighborhood is quiet. There is a store 2 min walk from the basement.
Very convenient check-in process (the host gives you a code to retrieve your keys)
The bad:
The neighborhood is quite filthy. There is almost always trash on the streets.
The room cleanness is bad:
- There were hair in the shower, as well as on the bathroom floor.
- There is a waist high grass right at the entrance - no one ever cuts it (those with pollen allergy - beware).
- There is a lot of trash right on the porch. No one throws it away (we were there for almost a week).
There were no sacks in the trash cans (kitchen and bathroom)
This is a basement with no ventilation, however there is a kitchen there. Which means that everything is greasy.
The neighbors above are indeed loud as several people have already mentioned (it seams there are several kids who are always running). However this bothers only if you stay inside. They are not loud during the morning and late evening.
Quite a lot of the "bad: list could be improved quite easily, however the result is as described.
Also I'd rather add something as a cleaning fee which could improve the experience even further (kitchen and bathroom need regular cleaning)
