We had such a lovely stay in Madrid because of this apartment and Guillermo's hospitality. It's a great location close to bars, restaurants, the theatre, metro stations and shopping, plus a huge flea market on a Sunday. The apartment itself is clean, comfortable and beautifully renovated to give an old building new appeal, but retaining it's original charm. I will definitely try and stay here again as we had just a flying visit. My husband and I would highly recommend this as a base for a Madrid visit and thank Gulliermo for his recommendations and conversations. Good luck with it all!
