Antonio's appartment has a good location. We had a great Xmas stay. It is very close to city center and there is a free garage parking available if you arrive by car. Lots of sightseeing can be done by foot including Turia Park and City of Arts and Sciences.
Antonio does not speak English but we understood each other and there were no problems in communication. Both Antonio and his wife are very hospitable, their appartment is cosy and clean, beds are comfortable and they also provide coffee/tee and some breakfast supplies.
I recommend Antonio's appartment to anyone planning to spend some days in Valencia.
