The apartment is huge, with a large living/dining area and three good sized bedrooms. There is air conditioning in the living area and the main bedroom and so they were very comfortable, however none in the single bedrooms so they got quite warm at night.
The kitchen is fully stocked and has a washing machine, meaning we had everything we needed for a our 4 day stay.
It is a little it further away from the city centre than we anticipated, it being a good 20-25 minute walk. I believe there are buses nearby but not really any close metro stations. However it is just a few minutes away from the city park and really close to the futuristic science park area. We got a taxi to the beach which was about 10 minutes and 7 Euro.
Our biggest thanks to Julia and Jaime for helping us to check in after 10.30pm as we missed our train from Madrid, Jaime is a great guy and gave us all the information we needed for a great stay!
