We've had a wonderful stay at their appartment. Marco and Carmen are undoubtly the best hosts in Spain, they are willing to help you with everything.
The room had excellent and comfortable beds and moreover was very clean, as well as the bathroom.
Our greatest joy was the amazing terrace with many flowers and greens, lovely to read/sunbathe/chill on it!
I truly recommend this place to anyone seeking a calm but sunny and lovely place to either enjoy the old centre of Valencia (10' with the metro) or the beach (15' walk).
Thank you Marco and Carmen!
