During our stay we experienced a major inconvenience. First, we were checked-in wrong apartment. We had to wait some time for our apartment to be prepared. Unfortunately, that was not the most uncomfortable part. On the first morning of our stay gas boiler broke and we were out of hot water. We reported it immediately and requested reparation. The woman who checked us in had a spare key so we left for walk in the city. When we came back in the evening the boiler wasn't fixed, host claimed it was our fault as we were not home when somebody was coming to fix it. But nobody asked us to stay home and nobody gave us a notice about when are they coming to fix the boiler and if we should wait for them. That was our only full day in Lisbon and we were not planning to spend it in the apartment. When we called woman who checked us it she suggested us to fix boiler ourself, but non of us had experience with fixing gas boilers, so it could put us in a dangerous situation. I tried to talk to the host, but he just kept blaming me and stoped responding at all. I tried to call but he was not picking up. We felt very neglected and ignored, the host behaviour was rude, unprofessional and inappropriate. On our last morning two guys came without a notice and fixed boiler. We took a shower and checked-out. I never saw host in person and didn't receive any explanation or apology from him.
