The apartment is hotel quality and it's in an antique flat completely restored, very comfy, extremely clean and situated perfectly in the center of the old town of Valencia. It is well equipped, even hairdryer and iron!
Walking distance to all main attractions, restaurants, pubs (there's a Starbucks to 100 metres); and 5 minutes walking to the Central Train Station and the subway towards the airport and the beach.
My experience with Gloria and with Airbnb was wonderful, I recommend it 100%. We would come again here if we return to Valencia in the future.
