The apartment is in an excellent location. The street is pretty quiet despite being so central and the double glazed windows cut out any noise. It has easy access to Opera on line 2 Metro just 2 minutes walk and is an easy stroll from Puerta del Sol and the Plaza Mayor. Well located for all the shops in Callao, we could easily come back to relax during the day. Unfortunately the roadworks at Granvia are disrupting line 2 between Sol and Retiro. The apartment itself has two double bedrooms but there is a large sofa bed. It is compact but very pleasant. The hosts were very helpful and welcoming. I’d stay again.
