My husband and I stayed at Carolina's apartment for 3 nights. It's in a great central location for all the attractions. Once we arrived, Carolina was waiting at the door to welcome us in. She was very friendly and a great Airbnb host. We were provided with a map of the city and Carolina talked us through points of interests on the map and made many recommendations. As we're more interested in the local people and places, she gave us many good tips on locals handouts, as well as things to watch out for as a tourist. Her mother was also living at the apartment and was very friendly and helpful during our stay.
The apartment is on the top floor (4th floor if I remember correctly) and has a good view of the street. There are 2 guest bedrooms with 1 shared bathroom and the family's kitchen/living room on the main floor. From what we could tell, the owners rooms are upstairs. Our room was as it's shown in the pictures - clean and well equipped. The bathroom was big and clean. The bedroom has a small fan and big windows to cool down the room. The only thing was that we found it too warm to close the windows so we did find it very noisy at night time. We didn't use the kitchen or the living area, although we're not sure if the area is shared with guests or not.
Our overall experience at Carolina's was good . Great location, everything was as advertised and mostly someone was there if we needed help with anything. Sadly we had to leave early for our train to the airport so we didn't get a chance to say goodbye properly (we left a note).
