Ilídio's place was very clean, quiet and well equipped — he even had fruits and a bottle of wine ready for us :)
He was also very friendly (he gave us a walking tour of the neighbourhood when we arrived) and responsive in our communications (he answered our questions about public transportation very quickly!).
The only downside would be the little bit of walking (minimum 10-15 minutes) required to get to major Lisbon spots. Lisbon is very “hilly” so this was a bit tedious.
I’d totally recommend this place for a couple visiting Lisbon!
