We had a great time staying at Moses place. It was very clean, the two beds were very comfortable and the apartment had everything we needed. You do hear the subway and noise from the street but we had earplugs and slept like in heaven. The loft is really nice, but it's kind of dark (it's in the basement) so we wouldn't stay there during the day. Communication with Moses was easy and quick. Very good host.
The location is great, it's less than 10 minutes walking distance from the subway (J/M) and close to Williamsburg centrum to check out the local food scene. You can also walk across Williamsburg bridge to manhattan (about 35/45 minute walk).
