Pros:
Parking! This is a big deal in Spain as garages are fairly expensive.
It is an extremely tight spot, so Judith was very kind to help squeeze our car in.
Very nice clean apartment. The terrace/balcony is quite nice, it is a great place to have a drink or meal or just relax.
Judith and her son are very nice. She gave us a map and recommendations of places to eat which was very much appreciated. She also nicely offered us some tea. Judith was very respectful about privacy as well. If we wanted to chat or had questions she was more than willing to help out, but was in no way overbearing. A great happy medium.
Possible Cons: Keep in mind that none of these issues would dissuade me from recommending this apartment, nor would bother a majority of people.
The room was quite hot and there is no fan or AC. I really recommend Judith purchase a small cheap quiet fan. It would have done wonders.
It was hot, in part, because we did not want to sleep with the window open. 2 reasons for this: Noise. Though not in any way on a major street there is still a fair amount of traffic noise as it bounces off neighboring building walls. This will not bother anyone who can sleep with windows open in an urban environment, but I am a light sleeper and couldn't do it. Also, there was a fair amount of fly/mosquito action going on. Judith had a little plug-in repellent thingy, but nothing is fool-proof. With a little fan and not being an extremely light sleeper, these issues won't effect most of you.
Judith's son was super sweet and cutely welcoming, showing us our room and bathroom. I thought that was a nice touch. However kids will be kids and aren't always the quietest.

I often find hotel decorations tacky, but at the same time, there was zero decoration in the room giving it an oddly sterile atmosphere. The bed was firm (not out of the ordinary we found in 7 rooms in Spain).
