The location is perfect to live the city center, in 5 minutes you can reach most of the restaurants / pubs / disco all around. In 10/15 mins you can reach the beach.
The flat is big, we were 3 but it can host up to 6 people. The living room is big enough to relax all together, thanks to the big sofa and the space. Kitchen is little small but you since you are on vacation it's way better to go outside to eat, spanish food deffo worth.
