Great location, couple of minutes from the metro station, the metro from the airport takes 20-30 minutes.
10-15 minutes walking takes you to all the sights (cathedral, central market etc).
Right across the road is the train station if you need to use that and next to that is the bullring.
I took a metro to the nearest beach stop and from then was about 15 walking to the marina.
Apartment was clean and everything provided (towels, toiletries), even had water and coke in the fridge for my arrival.
Only small negative was size of the shower cubicle, I'm average height and did find myself banging the sides, someone taller might struggle a bit more.
Overall a great stay and would definitely recommend.
