Tiago apartment is a 10 minute walk from the metro, but if you are taking the metro with luggage be prepared for a climb up the hill (like most places in Lisbon) the apartment is well furnished and unbelievably quiet in the evenings, we were there 5 nights and noise was never an issues, not even close.
The apartment is very comfortable, everything you would expect from an air bnb, but Tiago is a great host, he checked in regularly to make sure everything was ok, gave some great suggestions on places to eat and made us feel very welcome.
A great place for a stay in Lisbon, even the 28 tram stop is at the top of the road!
