Great Location. In front of Plaza Callao, although it is busy, night and day, the noise does not bother you as the windows are anti-noise. It is just a few steps from Callao Metro Station and Gran Via, with many restaurants, bars and shops nearby, including El Corte Inglés which has a supermarket and FNAC. You can go to several points of interest by walking.
The apartment is comfortable, clean and bright. Great for four people and seems to have been furnished and equipped to be functional with no major concerns with decor but perfectly meets the purpose.
I highly recommend it.
