We had a fantastic time in Valencia which is also due to our apartment and the great host. The place is very much recommended for younger travelers on a budget. You can reach Russafa (nice bars night life) within 10 minutes of walking and the city centre in about 20 which was very convenient for us (unfortunately we only discovered the bus number 6 in our last two days which is going directly to the centre). We spend a week in the apartment and it was perfect for 2 people (with six I imagine it to be a bit small though). The kitchen is well equipped and you have everything to feel comfortable (the only thing is, that the apartment is a little bit dark because it has just one big window with natural daylight - but this did not bother us because we were out to explore the city the whole day anyways). The host was super nice and very welcoming. It was no problem to deposit the key (as we arrived after midnight) and we got great tips for sightseeing. Thank you for kind help and flexibility, we will come back next time!
