When coming to Lisbon, my husband and I am glad we stayed away from Barrio Alto because it is so noisy there. This place is a beautiful get away from the main hustle and bustle and one can enjoy great scenic vantage points and visit the flea market on Tues/Sat just on top of the hill. With a transport hub a few blocks away, we had access to everything and even went to Porto. Remember that it is 4 story walk up, but after all the walking in Lisbon you'll be used to that. Also know that there is fresh linen in the drawers by the front entrance. Enjoy a great stay in Lisbon at Diana's and dont forget to eat lots of pasteis de natas!
