Location, location, location!! under 5min to Puerta del Sol and within walking distance to all major tourist destinations. Apartment is cosy and very well furnished. Esti was lovely and very helpful, greeted me on arrival and had helpful tips for restaurants and supermarkets nearby. The apartment is on the 6th floor, and the elevator is being fixed, so big heavy suitcases might be a tad tricky, but apart from that, the exercise was nice :) Definitely recommended.
