Very good place very well connected near the street food restaurant(open until late) and a bakery-caffè on the corner with freshly made pastries. The flat is located in the very center, 600 meters from most of the cultural attractions, and 200 meters from a well furnished shopping street.
The flat has two air conditioners and comfortable beds and four international electric sockets, so if you are from the UK or the US or Switzerland you should be able to plugin your devices. The owner replied my question until very late which were a relief, especially for newcomers.
