The place is a nice one really close to the beach for either summer time sunbathing or low season walks.
It is definitely smaller than it looks on the photos. The lower level of duplex is on ground floor, so windows are tinted to provide some privacy and you will not get any daylight at all, just hints of it. The upper level has transparent windows, but the building is on a narrow street anyway so the view would be to opposite flats and not much sun (bet otherwise it would be an over during summertime). During mid-season the apt is quite chilly if AC is not on most of time (noisy!).
Wi-fi, the first option was very slow (~1Mbps), the other, that the host provided after the message, first had about 4Mbps down and after another reach out, when host physically rebooted the router, it went up to 20. So consider it if you plan to do some nomadic work.
Kitchen us quite small and if fine for a breakfast, but not enough to cook any sophisticated dinner, so plan to eat outside
