A very nice, well furnished, clean, spacious apartment with great location - historical city centre is within walking distance, supermarket is just around the corner, there are great places to eat nearby. All in all, great place to stay, Carlos was very nice and helpful.
The only thing that we, a young family (no party goers) had problems with, was the street noise. The apartment overlooks a very busy street, which during the weekend becomes super packed with cars and people until early in the morning. So, bring good earplugs with you if you want a peaceful sleep. :)
