We had a good stay at Mirko's place. We were welcomed by his colleague, Cristina, who was very friendly and helpful - moreover, she waited for us even though we were half an hour late. Moreover, she arranged a taxi for us on the morning where we had to return to Denmark.
The apartment is fine and spacious for 2 persons. We did however have problems with the shower, where there was only very little water - and the drain was cloaked. We told Cristina this on our second day, and she promised that the owner would look at it, however nothing happened. We hope this will be fixed for the next guest.
All in all, our stay at Mirkos place was fine. The walk to the Sct. Peters Church is only 15 minutes and the city center, you can reach in 30 min. There also run busses to the center and a metro not to far away. The neighborhood of the apartment is however not that cozy, and Cristina also adviced us to go home by a taxi by night. However, we mainly went home by bus as we didn't return too late.
