We had a nice time in Artan's appartment. He was very arranging with us regarding our arrival, since we did not arrive at the usual check-in schedule. And he booked a transportation for us from the airport, which was very convenient. Joanna explained everything we needed to know upon our arrival.
The place was clean and convenient. We just had some noise from the neighbours one night (but we think they maybe were moving from their appartment), and the appartment is a bit dark, but when you visit the whole day and come to the appartment to rest at night, it does not matter.
Finally, the appartment is away from the noise of the street and VERY well situated, about 5 minutes maximum to the beautiful Duomo, which is a gem. I recommend this place.
