We had a nice, comfortable three nights here. The room, apartment, and building are very charming. Linh was very friendly and helpful, a great host. We did find it noisy next to the railway and are surprised that previous guests describe it as "quiet". You hear the trains and announcements, even with the window closed. Before arriving we had an issue with Stefan: I sent him a request to change a one-night reservation to three nights, which he ignored for several days (I even sent a reminder). So I cancelled the existing reservation and instantly rebooked for three consecutive nights. What I didn't realise was that it was too late for free cancellation, so I double-paid even though I instantly rebooked the same place and dates, so I asked Stefan to refund the amount I double paid. He refused, dryly mansplained how I should have made an additional booking instead of cancelling. He pocketed 64€ more than he should have and never bothered to even say he was sorry for the situation or for ignoring our original modification request. Strangely he didn't talk to us or even look at us during our whole stay, so there was no way to clarify what the hell happened. Linh kindly gave us a couple beers, but that doesn't make up for the 64€, which is a lot for us. (Airbnb agreed that we were in the right, but that a refund is the host's decision to make.) Anyway, it was an unfortunate situation and unfair that they kept the money, especially since I was trying to extend our stay (which means giving them more money!)
