As others have said Javier and Carmen are delightful people and have made a small apartment very beautiful, functional and modern. Again Javier made many useful suggestions on what to see and where to eat- thank you:-)
Opening and closing the Sofa bed is very easy and quick but do be aware it is a sofa bed.
Unfortunately downstairs is a small bar and as it was the weekend that was quite noisy. Otherwise for location and price and welcoming hospitality i recommend this place warmly.
