We had a fantastic time in Valencia, a wonderful city and the appartment is based in a great area with everything you need. It's close to the old city with easy access to the beach by bus. We hired bikes and Rufassa has easily accesible cycle lanes.
We didn't meet Raul but communicated via text easily. Maria was there to greet us and even though we could not speak each others language she was able to show us everything we needed and kindly left us a bottle of wine!
The appartment ihas everything you need, is clean, quiet and comfortable and the ceiling fans meant that it's not too hot in the night!
Raul has produced a guide to Valencia which came in useful and we ate at quite a few of the recommendations.
I would definately recommend this apparment and hopefully will be back to visit again.
