I have lived in Madrid and Valencia. I know Barcelona and Seville. Valencia is by far the easiest place to live. Highly recommend it.
I have lived here for 13 years now, previously in other Cities.
Fantastic restaurants, parks, aquarium, zoo (Bioparc), culture, museums,entertainment, clean, historical celebrations such as Fallas and Tomatina, the people are very friendly, bars,clubs, shopping centres, beaches, lakes, mountains,the list is endless.
The only thing I don't like about Valencia is the humidity in August. Can't stand it. My favourite month is October.
