Great location - lively but safe - with plenty of great places to eat and drink nearby. Really closed to Centro, too - Puerta del Sol is an easy ten minute walk.
The apartment is cosy and neat, with good facilities. Everything was immaculate when we arrived and the check-in process was easy. There was regular (but unobtrusive) communication throughout our stay from the hosts.
All in all, highly recommended - we'll come again!
