We had to find this property late at night and had trouble finding it but our friendly host came out to meet us and we were soon in our apartment.
There are lots of Cafes and bars in the area and a 2 minute walk to Callao and Gran Via 10 mins to Sol.
The only downside It can be a bit noisy at night especially when the night club turns out.
The apartment was good and as described, small but perfectly formed, with everything you need including a bottle of wine. The bed was very comfortable which was welcome after a long day in Madrid.
Our flight was an evening one and were able to leave our bags at another apartment allowing us to spend a hassle free day in the city.
All in all a pleasant stay.
