Salvatore's apartment was wonderful and his communication was perfect. He was also very accommodating in that we were able to leave our luggage in the apartment while it was being cleaned from the previous stay before actually checking in. Had there been no one else before us that day, he would have let us check in earlier as well.
We had a bit of a hitch getting into the apartment (got the key but apparently we suck at using keys and couldn't open the door) and he responded to us right away.
The apartment was a very short walk to both a tram stop (to get into the inner city) and an obb station (which has a train going to the airport). Also a decently short walk into the old city as described.
The apartment itself was very spacious and as described. Just note that there's no shampoo/body wash etc provided (or we were just blind maybe lol.. Very possible)
