Stayed for two nights. On reading the instructions, the self check-in seemed complicated but was actually pretty easy! And convenient (arrived 9pm). Location is GREAT. Mini market shop directly opposite, close to all amenities, bars and restaurants less than 5 minutes walk to Plaza Mayor. Apartment was nice and warm for a December stay. Everything easy to use including Netflix on the TV. Lovely hot waterfall shower! Only bad points being corridors of the building smelt of raw fish (not inside the apartment itself), only one small pillow each (I could have asked for more but didn't bother me that much to ask host). And be aware the shutters to the apartment's only window don't close properly due to the newer window's handle that gets in the way so we had to wedge a bag against it for privacy / overnight. Not the cheapest option. But overall a lovely little stay.
