What is not to like about a book store with a coffee/lunch spot inside where you can immediately dive into your new bought books! This bookstore in the centre of Madrid is a beautiful old three floor building where you can easily spent a few hours sniffing between all the books, notebooks and other stuff they are selling.
Mercado de San Miguel is an indoor market next to Plaza Mayor. I really like Plaza Mayor, it is an amazing and impressive plaza to see, and I love all the little balconies from the apartments with the plaza view. But I don’t really like all the terraces at Plaza Mayor, there are mostly tourists and the restaurants charge tourist prices as well. But just around the corner of Plaza Mayor you find the really nice Mercado de San Miguel. Of course, located in this area, this is not a cheap place as well, but at least its super cool!
