Someone broke into our apartment. The hosts traveled far from Barcelona, couldnt take my phone calls because they didnt have reception in their phones, werent serious enough to find a land line. They responded with generic text messages like 'are you ok' but wouldnt do anything. Since I figured that they are not serious enough to stay around should anything like this happens, and since nobody bothered to call me back for days, I'd say their work as hosts lacks proffessionalism and not serious. A serious host should stick around to help the people who paid enough to have some one they can trust. The apartment was nice but it does not have any backup and your hosts choose to travel away.. Think what can happen if you lose your key and there is no one to give you a spair one...
Bottom line did not do their job right.
