Had a great couple of days in Lisbon and didn't want to leave. The location of this apartment couldn't have been better - we loved seeing the river, walking round the corner for evening drinks and getting into the rest of Lisbon was easy by foot.
The apartment was quiet at night, however during our stay they were preparing for a festival so there was a lot of construction during the day, so can't comment on what it would be like normally.
Lastly so great to be close to the Castle and the other viewpoints. Highly recommend staying here in Alfama!
