This location is unbeatable. Plaza de Callao is a great spot accessible from everywhere, super easy to find and walking distance from most top attractions. The bedroom give to the plaza itself, so you wake up with the view of the city in all its glory. The windows are surprisingly sound-proof and really keep the street from coming inside while you sleep. The apartment is also stylish and just right size for a couple. This is my second time, and I will return :)
