Thanks to Marlene and Ivan for hosting us the last days. Communication went super smooth and friendly, the apartment itself is everything you would expect it to be, based on the informations shown on Airbnb.
Because of some plumbing issues in the other studio (that is right next door) we were offered accommodation in the larger one next door, which we really appreciated. For that particular studio the only thing we really didn’t enjoy was the mattress, since it seems to be considerably outdated (you can really feel the springs).
Besides that I stand with what I said, thanks for everything, would recommend staying there.
