The apartment is very nice and kids friendly, the kitchen is well equipped. A bus station is downstairs and a tramway station is across the street.
Emilia is a very kind and helpful person. She gave recommendations about restaurants, transport, shops... When we arrived we were surprised by the "goodies" she left for us, wine, juice, water... We even went home with gifts from her.
When I'll go back to Valencia, this will be the first place I will check.
