The location is great! You just open the building's main door and there's always something going on. Walk to Plaza Mayor, Puerta del Sol and other tourist places or stay around and hang out with locals at interesting cafés, coffee shops, bars, restaurants and shops. Lots of original, mom and pops places but also close to great supermarkets. Close to metro station and the rest of the city. The apartment is super nice, comfortable, updated, modern and very quiet, despite being in the middle of everything. Check in was easy and host sent very clear instructions with pictures. I'd return if I come back to Madrid!
