I loved Vienna and Nadia's place certainly contributed to that. The location of her flat is in a fun neighborhood with easy access to public transport. We did have some difficulty checking in. We tried to check-in early with Nadia's blessing but the restaurant next door where the key was stored was closed and had no posted opening times or contact information. We waited for a couple hours in the rain with no sign of it opening. Eventually a neighbor helped out. Nadia was easy to reach and apologetic. Aside from that, and some spotty internet, the rest of the stay was trouble-free. Clean and beautiful apartment with a lovely terrace. It is indeed 5 floors up (9 if you count each landing) but it was a good workout. Thanks again!
