Joana and Nunos place is just great! Joana gave a lot of tips for the city and restaurants. The apartment is rather small, but totally fine for exploring the city. It is clean, the bed is comfortable, there is a small supermarket just a few steps away, and you can walk basically everything. There is a washing machine (beware! You need to dry your clothes “old style”, i.e out side the window, so bring some pegs) and a dish washer available.
Since the windows are not sound proof, bring some earplugs, if you have a light sleep. There is not much traffic on the street, but you will still hear it though.
All in all we had some very nice days in Lisboa. And this apartment played it’s part very well. I can totally recommend it!
