Carlos's place is in a very quiet apartment building which I appreciated. Yet it is also accessible to the Metro (10 mins walk), buses (a number just a block away) and also just one block from the Turio Gardens. There are also supermarkets, banks, cafes and all manner of shops all around.
Carlos is a great cook and is very knowledgeable about food and cooking and had some great recommendations and tips. Both him and his son Lucas who was staying with him answered all my questions, were really helpful and helped make my first stay and visit to Valencia a wonderful experience.
