We booked the apartment literally two days before our departure. Ricardo responded within a few minutes after my first request - I've never booked a hotel that fast in my entire life. We couldn't meet him in person though because our flight was 3 hours late but he was available over our stay. His super nice parents met us at the train station, showed us the flat and told us everything we needed to know about the area. The flat was a huge surprise since it looks even better in real than on the pictures! It is modern, very clean and spacious. Don't be fooled by the nearby main street either - it's very quiet inside the building and isn't a problem at all, and we slept like babies on those huge beds. Just 2,5 kilometers walking distance from the historic center it's also the place with the best price-performance ratio. All in all our stay was extremely pleasant and we would recommend everybody who wants to spend some time in Valencia to stay with Ricardo!
