In the end we had a good time, but check-in was a serious problem. Check-in instructions were not sent in advance - there was a cryptic four-digit code instead, which turned out to be meaningless. The host listed on the site didn't respond when we realized we could not get in, and then it turned out 'Evelyn' doesn't actually live there. We weren't even sure which building to get into, and as we tried to enter what was actually one of Google's buildings in the area, a woman who happened to look out from her balcony in the correct building saw us struggling, let us in and helped us get to the correct apartment. Without a way to contact the host, it was only a matter of luck that we were able to get in. Once we got in, the actual host's roommate was very helpful and kind and in the end we had a very good experience. But the check-in was a real problem.
