Leonardo was a really good host. Even though we didn't even meet him personally, he made everything very easy for us. Instructions due to our arrival and check in were very clear. He also responded to our questions immediately and always fixed everythin if there were something to be fixed (for example problems with wifi).
Apartment itself was nice and well located. It was 15min walk to the train station and from there 10min to Venice or 1h 15min to Verona.
Only negative thing to say is that there were some black hair in towels and sheets, so we had to clean those before using them. But that wasn't a big deal since everything else worked so well.
Altogether we really enjoyed our stay in design house, and we would recommend that to others as well.
