We stayed at Sophie's place for about a month. It felt like we were home for the entire length of our stay.
Location: Perfect location, on 14th Street, the bus stop is right below and there is one across the street. The subway station is connected to practically every line. Lots of restaurants and stores around.
The Apartment: It is lovely and clean with lots of sunlight and plants. The kitchen is equipped with everything we would ever need, we cooked quite a bit and brewed our coffee every morning. The couch and the bed are extremely comfortable. We did spend some time working and there is a lovely desk by the window for that.
The apartment is much nicer than it is in the pictures and our hosts were very easy to communicate with. I would highly recommend this apartment for a short stay or a long one. No cons that I can think of at all.
