I have used Airbnb for years and this was an awful experience. Do not leave the keys in the door. This is written in the instructions but it is not written that if you are locked out of the apartment you will need to pay for a locksmith and repairs. Diego did respond but then made it sound like a major inconvenience to ask for help. I also felt as though I was being ripped off for the price of repairs. I asked this to be addressed as I had already paid the lock smith the night he let us in. When I asked for this to be addressed by Airbnb I received continued threats and was berated from the host. Very immature and scary. It escalated quickly and I did not feel safe in the apartment based on the messages I received from the apartment host.
The apartment does have a nice location. It is very run down. Missing tiles, mold. It is not worth the money. Save your money and book with someone less expensive.
