First thing I must say, the hotel is not Melia anymore, now it belongs to MCA hoteles.
I stayed there with my wife just for on night, but I think it was enough time to write a review.
When I was doing check-in they ask me if I want to park my car for € 15, I accepted and the staff took my car and brought it again next day without knowing where the car were. So I had no problem to find a place to park and no headache about security. That's good.
The hotel is located right in the Plaza de España, the centre of the city, so everyplace it deserves to be visited is a walk way distance.
Room was spacious, clean and hot, wich was good because the night was chilly.
I didn't take breakfast because in Spanish Hotels is an extra, so I went to the main square in front to eat at a coffe-bar, like other guests (it's a 5star breakfast with a 5star price, has you can guess...).
About touristic routes you just ask at the front desk, they explain you all. Nice staff.
I recommend it, for some reason is a 5 star.
