The first time we went to ibiza we decided to spend one night in San An so just arrived and found the first cheap hotel we could.
It was on that main street with the KFC etc, about halfway up the hill.
What a shithole - the room was totally basic, no facilities at all (we thought it was lucky to get a shower) and no fan or aircon. In the daytime it was quite cool but when we got back from Es Paradis in the early hours the place was a sweatbox - all the heat from the day had worked itself through the walls and heated the room through the night - uurrrgh.
We weren't gonna get any sleep, but if we'd wanted to this would have been very difficult. You had to have the window open for ventilation, and the noise coming from the street was unbelievable - screaming, shouting, broken glass, dustbin lorries etc.
