Almost 24h without any answer from one of the people whom I had spoken to prior to the day of arrival, which could have implied not being able to enter the apartment aonde whole night;
there was no light at the doorway, which was where the washing machine, ironboard, etc, were; the table and chairs outside were filthy; very simple area to hang clothes, and very dubious pictures on the wall (2 different young women in very unnatural poses for a "design studio", as it is called. It would be no surprise to find them in a calendar on the walls of a garage); and more expensive than another I found afterwards, which was incomparably better.
Apartment is nice; city is great; communication with owner was not good. TV was not functioning well and we reported this. Owner asked pictures of TV and remote control. We provided several pictures on second day, and then.. silence. No reaction AT ALL! We asked several times, but nothing. Even no sorry.
