I had a great time staying at Angel's apartment.
It is beautiful and spacious, like you see in the photos.
It is located in a less touristy area, but still close enough to places of interest - which is what I was looking for.
The spacious living room, with its huge windows and cool Spanish CD collection, was great for relaxing at the end of each day.

I did feel some lack of personal touch though, which one would expect from an Airbnb stay, for example:
There was no available soap in the shower, or dish-soap in the kitchen.
There were various coffee machines in the kitchen, but no coffee.

But overall, the beautiful and comfortable apartment compensated for these small disadvantages.
