This flat is so perfect. It is extremely close to everything you will want to do in Madrid. We walked everywhere.
We had small luggage and are fit to walk up a small stairwell almost 5 flights up, but if you can manage you will be rewarded with an affordable and stylish flat with incredible character. Open the windows on a sunny day and listen to the sounds of Plaza Mayor below and smell everything you want to eat during your stay.
We would highly recommend staying to anyone as we will definitely be visiting again!
