the room where I resided was quite loud since buses, cars and the tram pass by frequently, but with good earplugs you will find your sleep late at night. ;) other than that i had a great stay in lapa. the area was close by a lot of shops, cafés, etc. you can even walk to cais do sodre and to any other nice areas. antónio and his guest friend b. were very nice, helpful and welcoming. i mostly did not meet any other room mates but just 1. thank you so much to make my stay wonderful. all the best! :)
