Me and my girlfriend had a lovely stay in Anna's place.
She explained everything very well at our arrival and she gave us a few tips concerning restaurants and walks.
As for the apartment, we had no issues at all. It was clean and had everything that we needed. The bed was comfortable and the shower was nice.
The location of the apartment was good, too. Just a 10/15 min walk from the city center and 5 min away from the bus station. This was very convenient as we had to catch a bus early in the morning to Vienna.
Overall, we had a fantastic experience.
