We stayed there 5 nights. Check-in and check-out went very easy and uncomplicated. The apartment is perfect for a short stay and the necessary things are provided. It is on the 13th floor on a building of the top of a hill and you have an incredible sea view from the balcony (although it is not directly on the coast). It is an older building which was probably quite fancy back in the days, so is the apartment. You should not expect a super modern apartment, but it is quite nice and provides everything you need for your stay. And the wide window front on the balcony definitely enhances it.
The walk to the city center takes about 15 min. The way back is kind of annoying because due to the nice location with the sea view you have to walk up that hill. We walked a couple of times but in the evening we mostly took a quick Uber back.
P.S. There is an TV but there is apparently a problem with the cable connection so it did not work. First we thought the battery of the remote is low and bought new batteries. But that was not the cause. So if you have the same problem: you can skip buying new batteries:)
Nevertheless it was a nice stay and we would definitely recommend it! For us, it was perfect!
