I find it really hard to put into words just how incredibly amazing Rosa and Jose are, and how pleasant our stay with them was. Even though they don't speak a word of English (and we didn't speak a word of Spanish) we never had any issues in communication whatsoever.
Rosa went above and beyond to help us in any way she thought we might appreciate, even going to borrow a thermometer from her neighbors (at midnight!) when we had a severe sunstroke earlier that day and weren't feeling well. Also, the apartment was perfectly clean and comfortable.
After all, we can offer only the sincerest recommendations for both Rosa and Jose, and their place, as they really made our stay in Valencia much more beautiful.
