If you have heavy luggage, it's a bit inconvenient as it's on the top floor without elevators (just something to keep in mind)! Otherwise, it's on a very good street in Alfama... next to local diners, fado houses and wine bars. It's convenient to get to the Station.
The shower is tiny, so something to keep in mind if that's at all a concern. We stayed only one night as we were returning to the States the next morning, so we didn't get to utilize much of the space. But the location was great!
