I didn't meet Roman, the keys where exchanged at his bookshop, but the communication went great over the (airbnb) mail.
He responded quickly and was helpful.
It's a very mice place, looks like on the pictures, a bit old school and lots of books, a pleasure to stay there! I was there for work during the week and I was happy to come back in the evenings to such a nice place and my boyfriend came for the weekend, who liked it as well.
