This place is a great base for exploring Madrid. It is very close to Sol, Plaza de Mayor, Parque del Retiro, El Palacio Royal and the metro. The apartment is exactly as described and shown in the pictures. It is clean and comfortable.
There are many lively bars and restaurants located next to the apartment which is great, but the parties went on until around 5am. I'm unsure if the bars are usually that loud. It may have been due to various football matches being played that particular week!
Our flight was delayed and we therefore arrived after 9pm. This meant that we had to pay an additional €30 upon arrival. It does, however, state this in the advertisement and the housekeeper was waiting for our arrival.
Great communication with Carol throughout, thank you.
In summary, a great central apartment, but our stay was very noisy!
