Federico was a helpful host even though he was away for the duration of my stay. He checked in on me to see if I was ok or needed anything. Location is excellent as it's close to the sea, the City of Science and music (the park here is beautiful and a 40 walk will take you to the city centre). The metro is also close.
I hired a car as I planned to hike in more remote places. The only downfall for me is although there is free street parking, spaces are extremely difficult to find! I ended up having to hire a space in a multi story. Having said that, metro connections between the airport and Federico's is good. But check night time connections if you have an early flight.
The accommodation was fine for the price. Overall, I would recommend for the traveller on a budget. Thank you Federico.
