The apartment on Serrano street is a wonderful place right in the middle of the Golden Square as they call to that area. Lots of trendy shops, restaurants and walking distance to everywhere in Madrid. The check in was fast and they even lend me a plug for charging my devices. There’s no noise around so you will sleep like a log. The bed is super clean and comfortable. The apartment is tastefully decorated and is cosy and elegant. Don’t hesitate and stay here. Next time I’m back in wonderful Madrid I will definitely stay here again.
