We were greated by Gloria's husband, who was really friendly and helpfull, although he didn't understand English and we didn't really understand much Spanish. The apartment is really nice and has everything that you need. Gloria also provided us with baby cot and high chair.
It's in the town center, close to Valencias Cathedral and Torres Serrano. Sadly it's a bit far away from Metro, but really good located for exploring the old town center.
Sad we mixed up our dates, and stayed only one night.
