Great place to stay in Lisbon.
My husband and I stayed in the apartment 7 nights in January 2018.
Vasco was very attentive, to all our requests (like 2 sets of keys...).
The apartment is very well connected. Public transportation is 2-3 Minutes walk down the hill: central Metro line and the famous No E28 tram (take it to Graca than through Alfama...).
Next to entrance to the Metro there's great place to drink a cup of fresh coffee buy bread, sandwiches and the too tasty Portuguese pastry and there's a small grocery store right in front the apartment and 3 supermarket in 5-8 minutes walking.
And... last but not least, the justifiably famous seafood restaurant "Cervejaria Ramiro" is only 4 minuets :-)
We highly recommend Vasco place place.
