This is a comfortable place in a nice central area, near the castle and multiple embassies, with many cafés and restaurants nearby. The flat is clean, equipped with what you need for a short or a longer stay. Check-in and check-out are very unproblematic. The communication with the owner and his team is very good: fast replies, extremely friendly and helpful. There can be problems with mobile internet inside of the flat, due to the thick walls I think. But this should not be a problem with WiFi provided (there was no WiFi yet during my stay so I cannot say anything about it but I believe it should work now). In general, I liked the accommodation and can recommend it.
