I have to say this apartment is definitely worth staying at. This was my first time visiting Madrid and Harold took the time to tell me some places I should visit near the apartment as well as over Madrid when I was checking in. He also showed me a list (which is in the check-in binder) of restaurants that they've visited and recommend. The apartment was super clean and very enjoyable to stay at. Its located closely to shops, restaurants and markets which makes getting around to places easy. Don't have second thoughts, if this place is available book it!!
