I can just give all the stars to this place basis just one thing....Location Location Location!!!
The house is so well located that in the 3 days that we stayed in Madrid we were blown each day with a new realization that another 5 mins walk into a new direction would help us reach every place that we had planned to go to and few off which we did by cabs! Starting with the street just below the building which is one of the best Tapas lanes (Also featured in a James Blick video), to Batin Restraunt 50 mtrs away, Plaza mayor of course, quite a few interesting eateries and places in the Botin lane towards Plaza Mayor, I mean you name it and its walkable 5 -15 mins max! So if you plan to spend most of the time outstide (which you should, of course you are in Madrid!) then this is one of the best places to stay! No doubts here.
But......If you are very particular about the house you stay in (and I mean a bit finicky) then you will, like me may mind a few things. Word limit over....
