the only issue was the entry instructions. There were multiple sets of instructions. Apparently a set of instructions was emailed to me, but I couldn't find that. The ones associated with the app (where we are much more likely to go than email) suggested that we were in apartment 5 (1) and sent us upstairs, although they also said to use the lockbox for apartment 1. We were tired and didn't notice the half rubbed out lettering on apartment 1 lockbox saying ground floor. So it took a while where we were confused and trying many locks. The phone number connected us to the host's daughter quite quickly, but she asked which apartment number we booked for. Our app didn't tell us that information, so we couldn't answer that question. In the end it all worked out, and the outstanding quality of the stay made me forget all about it until now!
