There's a lot to love about Dan's place: the location, neighborhood amenities, character and history. It's spotlessly clean and thoughtfully equipped with everything you'll need to be comfortable; Dan is very generous with his invitation to guests to enjoy his piano, record collection, and technology. The moderate street noise that some others mention didn't bother us at all. And Dan himself is lovely -- flexible, personable, and extremely responsive when we had questions or concerns.
The only reason this wasn't a 5-star trip was because we encountered several hiccups -- a stubborn front-door key, a backed-up shower that required some plunger work, and a party upstairs with music being played at nightclub volume until 4:30 am (we didn't feel comfortable heading up there to ask them to quiet down - we didn't want to create a problem for Dan with his neighbors). We totally understand the quirks of historic homes, so the first two issues didn't faze us, but the night of lost sleep was a bummer. With a young child at home, we'd hoped this trip would replenish our sleep banks, not deplete it! In any case, none of these issues were Dan's fault, and he was very responsive to all of them (and has promised to speak to his neighbor about the noise) -- but they did affect our overall enjoyment of what is otherwise a fantastic NYC Airbnb.
All in all, we'd certainly recommend Dan's place and would stay here again...but next time, we'll heed others' advice about earplugs!
