Simon is quick to respond to requests. The check-in process was straightforward. The apartment location is excellent -- right at the city centre, within walking distances to the museums, restaurants, train stations and other touristy spots. The soundproof is a little lacking because the apartment is located and facing a busy street, I could hear street noise and people talking loudly on the street up until 2, 3am. I could also hear neighbours upstairs. It's a great place to stay if you are out and about most of the day.
