My wife arrived on Saturday afternoon at the apartment and it was extremely hot. The landlord associate noted the same thing and said the space should cool down. She stated the fans and air conditioning are extremely loud throughout the day and would not recommend staying in the apartment in the afternoon (not an optimal situation if you are with a young child). After a full day of waiting, the apartment temperature got worse. It was so hot it was impossible to be in the space for more than 15-20 minutes as the vents were blowing out heated air. We texted the landlords associate and immediately received a response back of "oops!" She quickly noted nothing could be done until Monday. The responses were so immediate we began to wonder if this was already an ongoing issue. I was arriving later in the day with our toddler and told my wife to go to a hotel as the space was not habitable. I called the landlord who informed us he owned the property since Feb and this was their first summer. I explained we only had a few more days and I would like a refund which he agreed to immediately. It seemed the landlord was going to resolve the situation with a full refund but THIS DID NOT HAPPEN. After 10 days, I had not receive a refund so I called the landlord. He stated he was going to refund my money outside of airbnb as it was complex and asked for my paypal account. When this did not happen I called airbnb who informed me refunds outside airbnb are not recommended policy. Airbnb is now involved for a resolution. Just to mention the apartment looked very good aesthetically but there was no door on the bathroom which is actually upstairs in the bedroom. This may be uncomfortable for most from a privacy standpoint. There were also some exposed wires in the bathroom looking as though there were some lighting renovations being done. Overall, beautiful apartment but not habitable in the Barcelona summer heat with the broken air conditioner. No matter how beautiful this apartment looks if it can not be cooled down because it is on the top floor it is not a penthouse it is an attic.We did not spend even one night in this apartment and look forward to providing all the information we have to airbnb to hopefully get the promised refund.
