A large, well-furnished and comfortable apartment in a great neighborhood. The roof deck was large and very sunny.
I was a little confused by the description of this as a "townhouse." I would call it a duplex apartment with a private roof deck in a multi-unit building. You enter through a hallway lined with other apartments to get to this one, and there are definitely neighbors.
The hosts were very responsive. They Ubered over a space heater--which was helpful, since I found the apartment somewhat chilly in late December.
