The apartment is centrally located. However it is positioned one floor above a hostel, sharing wi-fi. Two of the three bedrooms have windows on top of the hostel patio and this can become loud at times. The heating system is working through the ventilation and 90% of heat goes to one room. No instruction or details on the ventilation system were provided in the apartment. The host is not able to phisically support the clients, at least the service was not provided. We experienced a power outage for about 12 hours in the entire building with no possibility to prepare meals, take showers or use the lights! After communicating to the host via chat, I was asked to go and check with neighbours myself for info. After several hours I asked the host via chat about the situation, but I only had a reply the following morning, once the power was back up. In addition, some improvements would be required in regards to safety. In fact, power cables in the kitchen should be securely enclosed and glass door in the living room should have a secure lock. During windy days we found the glass door completely open and we had to secure it before leaving for safety concern. As we were robbed in a Burger King in Barceloneta during our visit, you can imagine that a door opening just with by the wind blowing could make us feel in the apartment...
