In one word: great!
The apartment, as well as its location were awesome. The apartment is just a 2 Minute walk from the city centre, which basically starts around the corner. The apartment itself is really clean and stylish. The cute, little balcony is nice, too. Having a Smart TV is also a "nice to have" in case you want to spend a relaxed evening at home. Around the corner there is a tiny minimarket in which you can buy some stuff to eat and drink and within the distance of around 200m there is a bigger supermarket called Dia.
Raúl was a great host, who also told us some places where to eat and go out. He is very kind and answers immediately if you have any kind of question. Another "plus" is that he also pays the service costs. I would definitely recommend this apartment and Raúl as a host to everyone else... it was a really nice stay.
Thanks/Gracias Raúl!
