The communication was easy and fast and Theresa helped us a lot. she is really kind and easygoing.
Is a bit far from cais do sodre metro station (1.5km), though in a nice part of town, where you can get cheap food and have a great sighseeing of "true" lisbon, often neglected by ordinary tourists.
althoug is a shared appartment, is really cleaned. our "roomies" were quiet and educated.
The noise on the street was tremendous. i know is not their fault, but i had a hard time to get to sleep, even though they had provided earplugs.
consider having a soft earbud with full noise reduction, and some chilling music to spend the night with you are affected by street noises as i am.
