We had a perfect stay at this apartment, which has everything needed for a comfortable stay. The whole place was spotlessly clean and very impressive. We stayed in February so the effective heating was very welcome and cosy bedding kept us comfortable.
Check in and check out was easy and convenient.
The location was perfect, a stones throw from Anton Martin metro station and within easy walking distance of Plaza Mayor, Plaza del Sol, the palace and many museums/galleries. It is in a pleasant and safe central district surrounded by great restaurants, bars and cafes. There is a bakery right across the street and minimarkets for essentials on the surrounding streets.
The only negative was traffic noise, as the apartment is situated on a busy road. However this did not bother us at all and was a small price to pay for such a great and central location. In fact, I enjoyed sitting with a glass of wine and watching the comings and goings on the street below.
I wholeheartedly recommend Daniel's place and will definitely stay again when we (hopefully) return to Madrid. A wonderful apartment in a wonderful city!
