Two minutes from the subway station Ventura Rodriguez, line 3 (yellow), the same line of Plaza España, Callao, Sol and Lavapiés. In less than five minutes you're in the centre of Madrid.
The apartment is near the Templo de Debod, Gran Vía, Plaza Sol, Plaza Mayor and Palacio Real. It's a great place for couples or young people traveling alone. The neighborhood is really safe and well communicate.
