I stayed at Mirko's place for about a week.
The place is very nice and spacious and is located in a very central place. However, the location felt a bit dangerous at night which is why I would not recommend the place for solo-travellers.
Other than that, the apartment was clean and communication was really great whenever we had any problems! The Wifi in the apartment was very choppy and did not always work which is why I would not book the apartment if you have important work to do and meetings to take.
Mirko was very responsive and the check-in process was smooth!
Would recommend.
