My wife and I enjoyed our stay at Carmen's house. Really, there was more space than we needed. It is a great space for a family. Recently renovated, clean and fully equipped. The wireless internet had the best connection that we encountered.
The home is located in the outskirts of Valencia but there is easy access to the Metro. We parked our motorcycle and used public transportation for the week that were were there. The Metro is inexpensive and convenient. One line takes you to the centre of Valencia in about 15 minutes. If you are driving, there is easy access to the A7. There are restaurants and stores within easy walking distance.
Carmen was great to deal with... friendly and knowledgeable. She met us on our arrival and showed us around. Also she has a well prepared information booklet (in English) that we found very helpful. If you enjoy staying in accommodation outside of the main tourist area, but with easy access to it, we recommend that you try Carmen's house.
