VRBO review: No air conditioning or adequate ventilation in our apartment

We are writing to formally escalate our request fo reimbursement relating to our stay at La Casita del Muelle, located at Calle Miramar 94, Taliarte, Telde, for which we paid 431.72Euros in advance or our arrival. Upon checking in on September 21, 2026, our host, Francisco, informed us that the apartment's air conditioning unit was not working and that a replacement part had been ordered. Unfortunately, this issue remained unresolved throughout our stay. Compounding the problem, there was no air-conditioning unit in the bedroom and no adequate means of ventilating the apartment. During our stay, outside temperatures were extremely high, reaching approximately 32 C. As a result, the apartment became uncomfortably hot and difficult to occupy. The conditions materially affected our ability to enjoy and use the property as advertised. We were unable to sleep comfortably, cook meals, shower without sweating continuously, or spend meaningful time indoors. Most significantly, we endured four days of inadequate sleep due to the excessive heat. Each day we contacted the host for updates regarding the repair. Each day we were advised that a repair technician was working on the matter, the issue was never resolved. Despite his attempts, the host was unable to reach the owner for suitanle alternative accommodations or addressing the situation. We paid 431.72 Euros at the time of booking a 100Euros security depost. The 100 Euros was returned along with an additional 50 Euros provided through the host. We later submitted a reimbursement request through Holidu and received only 14 Euros. The total compensation received to date is 64 Euros. After deducting that amount from the rental cost of 431.72 Euros, a balance of 367.72Euros remains. We are formally requesting a reimbursement of 367.72 Euros which we believe is a fair and reasonable adjustment given that a significant advertised amenity was unavailable and the lack of communication from the owner left us without a meaningful resolution while on holiday.
