Although we didn't get a chance to personally meet Roger, we did meet his roommate Olga and she was super nice to us. Roger was very nice too, he even mailed us the keys of the house before our stay because he was going to be traveling the day of our arrival.
The room was exactly as described and shown in the pictures. The bed was really comfortable, the apartment was clean, and their Nespresso machine was great :)
The neighborhood didn't feel unsafe but the subway stations were a bit further than advertised (10min walk to line 6, 20min walk to lines 2&3). It wasn't a big deal for us, but something to keep in mind especially during the cold weather.
Other than that, our stay was a great experience and we encourage everyone to stay with Roger and Olga! 😊
