The apartment is lovely and sparkling clean - exactly as shown and very stylish. The train station, Prado, Reina Sofia are all easy walks, the Porta del Sol and Plaza Major are a bit further but easily doable. The immediate surroundings are full of cafes and bars frequented by lots of young people - very fun but can get loud in the evenings. The apartment has great insulated windows, though, that filter out much of the noise. The streets in area can be a bit dirty - all those party people! - but seems generally safe.
