The house is ok, and the location is fine. The problem is really the host. When doing the check-in, the husband's host informed us that the AC was leaking and we had to empty the bucket occasionally. Well...there is 40'C in Malta, and as we realised after, the bucket had to be emptied every 3h. At that time, the host asked us our number so they could speak through whatssup. 2 days before we left we received a messaged asking if we broke anything in the flat. We found that quite rude and very disrespectful. We said we didn't and then they wanted to come to the house and check. In all my life, of staying during holidays in private houses, that never happened. Anyway, we accepted and said for them to come after 10pm, when we were in the flat. Shortly after, the host started to harass us and sending rude messages all the time, because her neighbor said that the bucket was full. So, they decided to go to the house, without our permission, and without us there. We felt that our privacy was invaded, and did not reply to any more messages. In the end, she still sent a message referring that we broke a curtain (!!!). Despite not being true, it's just mean.
Honestly, with so many houses in Sliema and S.Julians, don't bother staying here. If you decide to stay, please just speak through the airbnb plataform, so you can be covered from this kind of harassment.
