We had great time in Lisbon. It's a lovely city.
The apartment is perfectly located, close to public transport and you can go by foot to almost all major sights downtown.
Sofia and Jose are responsive and kind hosts.
Cleanliness of the apartment is OK, it needs some small fixes though, nothing major. It's a tiny, modest place, good for two persons who are travelers and need a well located, tidy place to sleep over.
I would definitely recommend the place and would come back again.
