The hosts were very great and helpful! Altough I could not speak Spanish, the communication was very easy and very fast. Rosa and Marco explained to us at arrival all the necessary things, gave us maps and showed us how to get to important spots (e.g. which bus to take, where we find the bus stops, which is the fastest way to the beach, where to find a supermarket, etc).
The apartment was very clean and looked exactly like on the pictures. There were even fans (one for each room). Also they provided all the necessary kitchen utilities and enough towels.
It takes about 10 minutes to the beach and in general the location of the apartment is good because all the sights and shops can be reached by bus very easy and fast.
The only disadvantage of the apartment regarding its location is the noisiness at night. Probably it is just the Spanish lifestyle, but we found it sometimes difficult to sleep at night because especially kids were still playing outside after midnight and screaming. Unfortunately it is so loud because it is impossible to close the windows since it is so hot at night.
However you get used to it and this was really the only disadvantage.
All in all, we totaly enjoyed the stay at this apartment in Valencia and would definately stay there again.
Thanks Rosa and Marco for all the help and for being such good hosts!
