It was great to meet Asier who is friendly and welcoming, even when we arrived at 22:00 in the evening. He showed us around the apartment and everything seems great. The beds are comfortable, the shower is hot, towel for everyone, and a well equipped kitchen.
One of the things I was struggling with is that there are no outside windows; so you barely get any daylight in. As it is end of November it is hard to judge whether it is raining or the sun is shining. While staying inside you have no idea about the weather, or even what time it is. Also due to the lack of fresh it can smell a little inside. For somebody who loves nature and fresh air this was a bit of an issue.
The location itself is perfect. Super close to the beach, ten minute walk to old town.
