We had a great time in Valencia and the appartment of Carlos and Petra is really very nice and clean. Located in the middle of El Carmen you can reach everything in walking distance. Carlos and Petra supported us very warm and friendly with a lot of information and tips of what is interesting to see as well as tapaz bars ;-)) The communication was very good in English.
We were quite impressed of this city - kind people, the architecuture, el Mercado central, la cuidad de las artes y las sciencias, the beach for taking a sun-bath or sipping a glas of wine in a nice bar while watching the sunset...
We felt very comfortable and enjoyed our stay very much. So we can honestly recommend Carlos and Petra as hosts :-)) and are very grateful.
