Toc Hostel.
It is situated in the most important area of Madrid, near Plaza Major and Plaza del Sol and this is a great position because you can reach a lot of different places in a short time.
When we entered, the receptionists appeared a bit disorganized because at our arrival we had to wait for the chek-in and when we entered our room the cleaning lady was still working.
The rooms are on five different floors connected by a lift and all the rooms open thanks to a fingerprint system so you don’t need any card or key that you can lose. Our room was quite big, with two showers, two toilets and comfortable beds but there wasn't space enough for all the luggage.
The breakfast room is very simple and beautiful but the thing I like most was the pool table in the center because you can use it all day long if there’s nobody who is already playing.
I will recommend Toc Hostel because it’s very modern,new and not expensive so if you want to spend some days in Madrid it is perfect.
