The location was ideal for the event I attended, and it was fun to stay in a brownstone, particularly in late autumn. Communication was prompt, and the space was immaculate, with a fast-working heater and plenty of hot water putting to rest my reservations about staying in an old building.
I did, however, miss out on good sleep at night, as the noise from neighbors, outside, and the building itself (plumbing, mostly) was much louder than expected and occurred well past quiet hours. I might have been entertained by a boisterous discussion on the virtues of noodles at 8 PM, but it was less appealing at 2 AM with an early wake-up call pending. And then there was a mouse--eek.
My experience was largely comfortable, however, and I would expect others to have a positive experience as well.
