We absolutely loved our stay at Marta's place in Valencia! We travelled with a toddler and the place has everything you could need - cot, highchair, baby bath, toys!
The apartment was spacious and clean, and there are supermarkets and plenty of cafe/bars nearby. And it's about a 15-minute walk over the bridge to the old town.
Marta was really communicative and gave us lots of ideas for things to do in Valencia. She was really friendly too - our toddler loved waving to her in the morning!
We would highly recommend visiting Valencia and staying here :-)
