Booking process was stressful due to need for late self check in. On the phone I was told that was possible, but afterwards I got emails saying I was not going to be let into the appartment after 11pm. Called several times each time a new person picking up the phone giving me inconsistent information. After many attempts I got the instructions for self check in on the same day I was traveling. That made me feel very uncomfortable since I was traveling with my little daughters. I started thinking on a fallback plan in case I was left outside at midnight. However, everything worked fine in the end in terms of getting in. The flat was extremly cold though. My daughter suffered a lot since it took more than 2 hours to have it heated. Everything else in good order.
