Justo's apartment was absolutely beautiful! We loved the amenities - we are used to staying in kitchens where it is very difficult to cook as you are missing most utensils, but this is not the case in Justo's apartment. We didn't actually do a lot of cooking (too many good restaurants nearby!) but could if we wanted to. He also provides many basic ingredients for cooking. The finishes are new and stunning (lots of marble!) and the apartment was really clean and comfortable. Laundry (washer/dryer) in the unit was helpful too since we were there for 10 days.
Our favourite part was the location. We were there with our 6 year old and visiting family with young children, and were a few minute walk away from amazing parks, the science museum and the aquarium. We hardly drove anywhere as we were a 15-30 minute walk to the beach and the downtown neighbourhoods with more restaurants/shopping/sightseeing. Valencia is a beautiful city and we found Justo's apartment to be the perfect spot for experiencing it easily.
Justo himself was friendly and welcoming and made things easy for us the whole time we were there. Highly recommend this place!
