We had a really great time in Valencia. Thanks Tomas and David for hosting! Even though there were some communication troubles (totally our fault) they were understanding and we had a warm welcome.
The location is great. The beach is really close as well as the metro lines to get to the center. We also didn't have any trouble with finding grocery shops and places we can eat out.
The apartment itself has a very authentic vibe to it, we personally enjoyed it. However I tend to agree with other commenters that the AC positioning could be better as it gets really warm upstairs, in the bedroom, and it's hard to cool it down. It didn't bother us as much as it could since we came in September and nights were somewhat chilly and there was even rain a couple of days, but I can see how in July it might become a problem.
Also just as a note to other guests: bathroom is pretty open. We went as a couple, so again, had no problem there, but if you're planning to come as a group that would've liked a bit more privacy in there it might be a factor.
Otherwise a pretty good choice to stay, thanks again :)
