I was only in Madrid for the weekend and I wanted a nice apartment in a central location and that is exactly what I got here. The apartment was great, small but stylish, clean and functional, plenty of room for my girlfriend and I, equipped with everything we could need.
The location was amazing, if like me you want to explore Madrid on foot, you can easily do that from here. Within a 25 minute walk you can reach nearly all of the major attractions, squares and monuments (most just 5/10 minutes away). If you prefer to get the metro then Callao station is less than a minute away along with the much larger Sol station with overground routes as well about 5 minutes away. We couldn't have been happier, just off the Gran Via with all the shops and restaurants as well.
Nader was great, very welcoming with a slightly early arrival and very kind to let us store our cases on leaving day so we could explore freely.
Highly recommended, would certainly stay here again when I hopefully return to Madrid.
