This is a basic apartment, not quite as nice as it seems in the photos but for the price, it does the job. If you are looking for a landing pad in Salzburg, it works. Salvatore is very quick to respond to emails, we did not meet but he seemed very friendly and helpful.
The good stuff:
-The bed was very very comfortable. We were in Austria for 2 weeks and it was the best bed we had. Nice comforter!
-The kitchen is pretty well stocked, we did a bit of cooking and found most of what we needed.
-Good location, especially getting to and from the airport. Lots of nearby public transportation, and very close to Belvedere.
-Easy check in/out process.
The not as good:
-We wish there had been more supplies. We were staying 5 days and were left with 2 rolls of toilet paper, 2 scratchy thin towels for the shower, 1 small towel for the kitchen, and 1 small garbage can in the kitchen (and no additional garbage bags). I'm sure Salvatore would have supplied more if asked (we did get 2 more small thin scratchy towels), but it would be nice to just not have to ask! Another garbage can would be really helpful in the apartment.
-There is a partial glass wall between the bathroom and bedroom, so that if someone turns the bathroom light on when someone else is sleeping, you are basically turning the lights on in the bedroom. Not much that Salvatore can do about that, but we found it bad design and a little annoying.
-There is a neighbor who smokes in the hallway right outside the door. The smoke comes into the apartment and it smells awful. Vienna is not the most pleasant place for non-smokers anyway, but this was a little too close to home! Again, not Salvatore's fault at all, but something people may want to know if they are sensitive.
Overall the apartment worked out just fine for us, but I don't think we would rent it again.
