Claudia's place is perfectly located, less than 100 metres far from the famous Gran Via. Puerta del Sol is just within 3 minutes walk. Also, three metro stations(Gran Via, Callao, Sol) are between 2 to 3 minutes away.
It's one of the best holiday apartments we've ever been to, very clean and equipped with everything that's necessary for a wonderful stay in Madrid.
Claudia was always helpful with everything we needed during our two-month stay! I would definitely recommend her place to anyone who wants to visit Madrid.
