We had a very pleasant stay in Prag. The appartement was in the middle of the tourist zone in the old town. With the windows opened we could hear the people on the outside well but with windows closed I didn't really notice. The appartement itself was really nice with everything we needed. We could easyly go anywhere by walking. Checkin and checkout was also great. We were driven to the office near the trainstation and could leave the luggage there. Totally recommend Alex & Kate!
