Pros:
Fantastic location (right off Via Toledo and close to great food and metro)
Great space (very clean and well maintained)
Great value for money
Washer and dryer ideal for long stays
Cons:
4 flights of stairs (difficult if you have large and heavy luggage so not ideal for long stays)
Rock hard beds (almost like sleeping on the floor)
Limited hot water (especially if both showers are being used at the same time)
No microwave (hard to make use of the refrigerator without a way to warm the food)
I would stay here again if I travel without large, heavy luggage and if the beds were more comfortable. If neither bothers you, this place would be ideal
