We had a fantastic stay. The flat has been refurbished and it appears that the whole building is for air bnb. Easy check-in and checkout. The flat is big and spacious and had the basics of everything you need for a short stay. Great WiFi with smart TV with Netflix and other apps.
Walking distance to Angel Guimera Metro. It was very quiet. The host was easy to keep in touch with even though we didn't meet in person.
We would definitely repeat if it is available when we come back to Valencia.
