Iryna's place is in a great location, the area is quiet and away from the main tourist areas but pretty much everywhere is a 10-20 minute walk away. There's a square a couple of minutes walk away which has some nice restaurants and a place to get an ice cream. The apartment is easy to reach from the airport, takes about an hour and the closest stop is Ospedale (line B).
There were no major issues or concerns with the apartment, we checked in fairly easily but Iryna wasn't available to meet us, we ended up waiting on Gianluca to arrive to check us in properly. It's worth noting that the second bedroom is pictured with two beds (into one larger bed) but there's now only one single bed - not a big deal but my friend and I picked this place because the bedrooms appeared to be pretty much equal. The smaller bed also wasn't made up properly, we sorted this easily by taking a cover off the other bed - again, not a big deal and easily sorted. Iryna's contact throughout was great, she was in touch with us pretty much every day to check everything was okay and I'm pretty sure that she would have sorted out the aforementioned niggles - we chose not to mention them because they weren't massive issues for us. Overall it's a lovely place and a great base to wander out from to explore a beautiful city.
