Such a great place in the center of Madrid near the Opera House. It's walking distance from so many great things like the Spanish Royal Palace, Old Madrid, Plaza Mayor, San Gines, Puerta Del Sol, Gran Via and conveniently located by several metro stops. This place was able to accommodate 6 people during my stay. It was clean, there is air conditioning, a kitchen if you want to cook anything, everything you could need Carlos has accommodated. Check in was very easy and Carlos answered any questions when I had them. I would definitely stay here again when I return to Madrid.
