We stayed at Miguel and Laia's place for 22 nights with our three young children and loved it. Both Miguel and Laia were genuinely kind hosts who enjoyed getting to know us, practicing their languages with us, spoiling our kids with ice-cream and sharing tips about Valencia.
In the apartment, we used the fourth bedroom as a play/cartoon area to keep the dining/living room free. The building had an elevator so we didn't have to carry our stroller up one flight of stairs, and the small private courtyard for the apartment was a perfect place to leave shoes and scooters that got us around town in the heat. We ate at least one meal a day in the apartment and had everything we needed to cook and dine as a family of five.
Any kind of store we needed on a daily basis was no more than 5 minutes away, including the mercado central. There was a plaza just outside the apartment in front of the school of design that we used to let the kids burn off energy. The Turia park was only 10 minutes away, and there were nearby bus stops, bike rental companies and a metro stop. Very conveniently located!
All in all a great place which we'd highly recommend to travelers!
