This is by far the nicest and best valued airbnb lodging of the many we have tried in Brooklyn. That it is also the closest to our daughter's place was an extra plus.
Mark's suite upstairs is very clean and beautifully renovated to also include things like enough and accessible electrical outlets of modern standards. We actually travel with adapters for the outlets when we go to BK, because it is not uncommon to find only old outlets that will not take a plug from a laptop.
The space is great for two people, even if you spend part of the day indoors. Four people would make it tight, both for moving about but also for having a place to put clothes and things.
