As with many other flats, you do not communicate with the owner, but with the agency - Urban flats. This unfortunatelly you get to know just after you book the stay, not before. The agency itself is some 500m from the flat. So if you do not have the self check in (which we fortunatelly had), you have to pick up the keys elswhere. The agency also tries to sell you other services - like overpriced transport form the airport (100 EUR from agency vs 47 EUR same way via Uber...). Also you can not agree with the owner for example later departure, again, you have to communicate with the agency, which will just sell you baggage storage fro 5EUR a piece. Personally, next time I will try to avoid the agency and look for the flat where you communicate with the owner. The flat itslef was very good, clean, comfortable, easy to find and access.
