Very central and relatively cheap. Small room with direct access to an alley. Quite charming except there is not much light or air coming from the really small tube-like window carved in the very thick ancient wall. No telephone signal inside, but there's wifi. The owner gave me the wrong address by mistake, but then he kindly helped me bring my luggages to the correct one. He also helped me when I left the place. The room was not properly cleaned until the day after my arrival. And there was some mold in the bathroom and a leaking pipe. They fixed the pipe and cleaned the wall with bleach. They told me some renovation will be done in the next future. I was promised a small compensation for the inconveniences, but of course this never happened... Anyway, the bed was comfortable and, apart from some faint noise from a vent from another building, it's quiet.
Considering the position, the air-conditioning and the relatively low price, it's a viable choice for short periods of time.
