My father and I had a great stay at Rosa's place. The house was very clean, and came with most household essentials (e.g. shampoo, shower gel, closet with hangars, etc.). Although we went sightseeing for all four days of our stay, I could easily relax for hours at home.
There were some weird issues: the WiFi power cable was missing (they gave a replacement); the washing machine was somehow locked (you aren't supposed to wash clothes at night because of the noise, we didn't check during the day), but we didn't have time to wait for someone to unlock it, so we used a laundromat nearby.
All things considered, though, we still had a very good stay.
