A clean, spacious, well-decorated place in the middle of LES, close to necessities and, of course, a lot of good food and nightlife. The place faces inwards, so it's not noisy. It is a walkup, and there's a coin laundry around the corner.
Stefan is a very accommodating host and usually replies < 1 hr. The first night I accidentally locked myself out, and although Stefan was away on a trip, he quickly arranged for me to pick up an extra pair of keys. (Thanks again Stefan)
Overall I'd say the place is great, and the price is very reasonable.
