We spent 5 wonderful days in the flat. It's very well located within walking distance of the main touristic places. The area is quiet but close to principe real's vibrant nightlife. A very good restaurant, Quermesse, is just around the corner (don't miss it).
The flat is small but cosy and well equipped. We only had some issues with the Internet connection that went on and off randomly.
Victor was very welcoming and easy to communicate with.
