Pros (+) This guest house was pretty good. The staff was friendly and the room (four-bed female dorm) was clean. I originally booked a mixed dorm because it was the only room available online, however the staff who checked me in said there was an opening in the female dorm and asked if I wanted to move. Very nice of them.
Cons (-) The rooms were a little awkwardly sized, even by hostel standards. From what I could tell, there weren't many bathroom options aside from the one in the dorm. It made for a bit of waiting in the mornings. The location wasn't too bad, but it wasn't great either. Not very close to any of the famous/popular sites, but that's what the metro is for.
