This place was in a great location on a quiet street near Plaća Sants. It is tiny, but comfortable. Pay attention to the part about the stairs. Once you get the luggage up or down, it's great, but there are a lot of stairs.
There was a problem with the toilet seat when we arrived, and they told us it would be fixed soon. It was fixed, but we used the seat with a duct taped hinge for 4 days. That was the only complaint we had.
Other than that, it was a great spot.
