We had a wonderful stay at Irena's brownstone, which was even better than it appeared in the listing. It's very much a "real home" that's spacious, comfortable, and beautifully appointed.
There are a few reasonable rules you'll need to observe, such as not wearing shoes inside, which mostly help protect the old home's and furniture's surfaces and finishes. And being an old home, you'll need to take care to make sure the doors and windows close completely (the large front door in particular.) You'll also need to be okay with climbing flights of stairs, which is part of the classic brownstone experience.
Although it's in the center of everything the Park Slope neighborhood has to offer, it was remarkably quiet inside. Restaurants of nearly every sort are just a short walk away, as is Prospect Park. The subway is also relatively close by, though we didn't need it during our stay.
It was easy communicating with Irena, who sent a very thoughtful and comprehensive guide to all the home's features. Check-in and check-out was easy, using a lock box system.
And thank you, Irena, for opening your home to us.
