I stayed five weeks in Adela´s apartment, half of the time together with a friend.
The apartment as such is great. It's spacious with a nice kitchen and at a good location. There is enough space for up to four people, just the small balcony won't fit everybody. Adela will welcome you before arrival with a nice manual which provides many suggestions and rules.
It was a great place to work, with fast and stable internet. Cooking was fun with a good inductive oven, a microwave and a big fridge. The beds are very comfortable and showers work as they should. We would have liked to have some more space for clothes as the master bedroom has only a small closet and in the smaller room the closet was a big damaged. Despite this everything you need is there, including a washing machine and a dish washer.
At the time of our stay, the sheets and towels were a bit worn but I guess Adela will change them soon to match the expectations you have for the price of the place. Altogether we enjoyed our stay at the nice apartment.
