We can highly recommend staying at Mabel's flat.
Mabel was quick and responsive with communication , very friendly and helpful.
Met us personally at check in,explained everything and a tour of the apartment (which is exactly as described and pics. It is a great space).
Great central location within 5-6 mins walk from a metro station which is on the line 3 (red line from the airport). Easy walking distance to central attractions and very easy to travel by metro. Although being central we found the apartment to be quiet.
