Make sure you get a proper contract if you rent with these guys. They were really friendly when we wanted to rent, but upon leaving the apartment we had to send repeated emails to get any of our deposit back. At which they tried charging us for lamps and work surfaces which we left in the same state as we got them. And we never got all our deposit back.
Tried claiming that we'd been told to do an inventory on the apartment ourselves, which is somewhat odd and not how it's done, yet their email stated that they were going to do it with us.... which they didn't.
There were also several problems with the apartment which they didn't really seem to want to fix.
Overall I would say to go with someone else through AirBnb so you get an escrow.....
Be very very careful with these guys
