Excellent location for all the major attractions Lisbon has to offer, good base location to get everywhere easily by walking. Plenty of shops, restaurants and attractions within walking distance. Others very easily reached by Taxi, Uber, Tram or bus.
Yes, the street is lively at night, but we had no really problems sleeping with earplugs, if you are a very light sleeper and go to bed early, then maybe not for you!
Can highly recommend this place. We did not cook as Lisbon has so many great restaurants.
