The flat is great, very nice looking, full of light and with a beautiful view. Communication with our host was impeccable and accessing the flat was very easy. The island is wonderful and very central. We had a great time!
One big downside however is the noise: the flat is located near the Tivoli amusement park, so you can hear loud screaming from people on the rollercoasters literally all day long. In the summer, the park also holds concerts at night and "night rides" until 10pm or midnight every day. We were there during the summer so we needed to keep the windows open but things are probably much quieter in the winter.
