Not clean enough: pieces of hair here and there, room was a bit worn down.
Nice small bathroom, but awkward hypermodern shower system difficult to operate with too many handles!
They could give a bit more soap.
Room had an interior window only.
Sound isolation was quite good, the bed was comfortable and wide enough.
Friendly receptionist and friendly cleaning lady. Very nice.
Within the accommodation facility you have to climb awkward narrow stairs. One wrong step and you can fall.
This is uncomfortable with a large luggage.
The photos show a much nicer image of the place. In reality it's a bit worn-down and not clean enough.
This room was around 80 EUR, but is worth less than 40 EUR considering all aspects. Still, it was the best option for me due to the good location near the Callao metro station.
If you really need a place to stay in the centre of Madrid and you can spend 80 EUR per night, it is for you.
Compared to other similar hostals in the area, yes it is worth. Madrid is very expensive.
But considering the value for money - it is not worth.
