Absolutely loved this place! Would definitely recommend it. It's huge and couldn't be in a more perfect location. Things to take note of is there is no kitchen, that didn't matter to us as we are breakfast, lunch and dinner out and there are trillions of amazing restaurants within 5 minutes walk. We'd particularly recommend both Frida and Tasca y Manolo. While if you want something more lively try Mercado de la Reine on Gran Via... Good was simply fab!
It's a little noisy so if you're not used to urban living you may want to take ear plugs!
Cheers Alex - you're a star!
