22 year old language learner looking for summer accommodation in Valencia

I am a looking for a single room to stay in this summer while studying in Valencia. I am coming towards the end of an 11 month stretch in Chengdu, China where I have been taking part in a Chinese language exchange programme. I am friendly outgoing person who likes to meet new people and experience new cultures. While in Valencia I hope to be focusing on studying Spanish as much as possible so am looking for a good study environment that's is ina fairly central location.
