I really enjoyed Valencia and the great location of Elia's room helped a lot! The Avenue where the house is situated is busy, supermarket is 3 min walk away. Bus stop is 5 min away, but I only used it once, preferred walking and metro. The nearest metro station Bailen is less than 15 min walk through Ruzafa, but I preferred to walk extra 6-7 minutes to Xativa, where fantastic old city center of Valencia begins. The Ruzafa area is very safe and pleasant, full of nice cafes and restaurants, and I have never seen anything dodgy or criminal even after midnight.
Elia is a very nice person, her cats are well behaved and clean animals,I have mostly seen only one, Trasto, a superfriendly animal) Elia gave me a lot of advice on tourism in Valencia, it was a very good stay! Make sure you ask Elia the number of the flat, since Airbnb gives you house number only.
