Christophe and Romana are friendly hosts with a nice apartment very centrally located with bus and metro nearby. The only problem is that they are unable to provide a key. They worked around this during our stay, sometimes letting us borrow, and even walking back to the apartment from an event to let us in. They were home often when we were there and very responsive so this was not so big an issue. They said they would work on getting the landlord to provide a spare key. Definitely stay with Christophe and Romana if you don't mind working around this issue! They are great and their dog is very sweet :)
