The hosts were fantastic! There was a problem with the apartment we initially booked, so they very kindly moved us to another apartment. We were greeted by a really nice young guy who explained the apartment and the local area to us. The apartment was very central to the old town and had everything we needed. It was perfect for a group of work colleagues visiting the city for a conference, but also great for sightseeing too! I would really recommend booking an apartment with these guys in Prague.
