The apartment was great. Everything you need to spend a great time in Prague. The apartment has really good furniture and renovation.
It located in a great area with a lot of good cafes, bars and restaurants and a bit far from the overcrowded old town, but you can reach it easily on the tram. The location is a bit mountainous so be ready to go up and down.
One very bad thing for us was the Internet. Wi-fi almost not worked, because of the router located behind the wall in another apartment which is always a bad idea. It has an unstable connection and 20-30% loss. If you need to do some work I'm afraid it's not really a good place, we have to go to a ​cafe to do work.
