Marco was very nice, hospitable, friendly and helpful. He allowed an early check-in and late checkout. He even stayed awake at night to let me into his apartment. He also gave me recommendations which places are the best to visit in Valencia and gave me directions to the nearest supermarket that is just around the corner. This, along with the nearby metro station, makes the apartment location just perfect for getting around the city and making purchases.
As for the apartment itself, it has a separate bathroom for guests, and this is a great plus for me. The only thing is that it is need of minor repairs.
All in all, I would recommend this apartment to anyone looking to visit the beautiful city of Valencia.
