Great Location close to the center within walking distance of Alfama and Barrio Alto.
The place reminded me of camping - I found it very damp (maybe it was just the October weather) and dark since it was on the ground level.
I wished it was a bit more private - you have to walk through the hosts apartment to exit and enter the accomodation.
I would say for a few days it is a great option - I was there for 10 days and would have preferred something more private. The wifi was excellent - which I appreciated as I had to work a few days.
