Well this didn't start so well; we couldn't get in because apparently the previous tenant hadn't left the key in the box - which means that nobody came to check the flat and clean it before our arrival time (we were about to stay 2 weeks in this place). We could get in only 4hours later, so we went on a food hunt whilst waiting (with our big suitcases), and they agreed they would pay for it as a compensation - to then say when we sent the bill that they would actually only pay part of it (I still haven't seen any sign of this money more than three weeks later btw).
Although it's a cute flat and very well located, it's not exactly what is sold on the ad: 51m2...? It's not even half of this (and as an architect I think I can tell what 51m2 looks like). Very noisy street, shower was very hard to use and washing machine wasn't working (also, when I informed the hosts they asked me to send a picture - what, of the washing machine... not working? Can you explain to me how you see this on a picture?). Anyway, not what I was expecting, I wouldn't recommend.
