We had a good stay at Alguera Napols apartments but it is a very basic place.
We found the beds very uncomfortable. This tainted our stay a bit as we slept very badly all week. The double bed in the master bedroom is so incredibly squeaky and our friends weren't able to sleep through the night as they were persistently woken up by the bed screeching. The sofa bed is also very uncomfortable, with a very thin mattress that folds up during the night.
There are two terraces which are really nice. We enjoyed using these for breakfast but the rooftop terrace gets extremely hot during the day (felt at least 5 degrees hotter than down on the street) and there is no shade, which meant we didn't use it much during the day.
Note that the air conditioning is only in the living room (where the sofa bed is) so unless you keep all the doors open at night the bedrooms get very hot.
Overall we had a good stay at Alguera apartments, however we felt that we could have got much better value for money elsewhere (we did stay during the Primavera festival week so perhaps prices were higher than usual).
