This place was excellent for our family of four during our first visit to Valencia. The location is right off the Mercat Central entrance (very short walking distance - like 400 steps) to the door. Plenty of great little restaurants and shops all within one block of the apartment. The restaurant closest (where went for coffee - cafe con leche every morning) was perfect for us and the staff speaks English if necessary. Taxi pick up was about one block away which made getting around very easy.
The apartment itself is very clean, looks just like the pics, great condition. Francisco was such a pleasure to deal with as the trip came near, during our check in and with any questions we had during our stay. He provides recommendations to great spots very near in the city. You can walk nearly anywhere in 15 mins to see so much. Entrance to the apartment is on the third floor, and, there is an elevator if you choose not to use the stairs.
There is construction happening on the road within 300ft of the apartment. You will hear the work going on during the day, but, this was not an issue for us. Being in the city, the noise was expected. I do not consider this a negative, but thought others may like to know.
We had a great time and made great memories at this location, I highly recommend!
