Terrible customer service and overall experience. I left the keys in the apartment as instructed for checkout. When I went to the main door, another resident locked it and I could not leave. I was trapped in the hallway for 2 hours and missed my flight. KeyBarcelona refused to pay for the locksmith I called and insisted that I waited for 3 hours because that’s when their office opened. I am extremely claustrophobic and it was a terrible experience for me. KeyBarcelona asked me to knock on every door in the apartment to ask them to help me open the main door and the residents ended up calling the police on me. After all this, KeyBarcelona still refused to reimburse me for the amount I had to pay the locksmith to open the door and any amount on top of that for the trouble it has caused me and the flight that I missed. Would not recommend dealing with this company especially after they did not reply me once I brought up the reimbursement to them.
