Jean Luc is one of the most responsive and communicative hosts I've dealt with. He took care of everything, from arranging for Fernando to meet us at the airport and showing us around the apartment and how to turn on the gas / hot water etc... We also had a bottle of porto waiting for us after a traditional cozido lunch at the restaurant over the road!
The place was comfortable and felt secure. Loved having the orange tree in the garden, they were great for breakfast each morning. Even smuggled a few home 😁
Found it was quite walkable but if you have anyone with you who's not a strong walker (especially with hills etc) then it's relatively cheap to get taxis or Ubers to the various neighbourhoods.
The nicest thing was getting back to a quiet cosy apartment after a long day walking around Lisbon. The wifi was fast so we were able to watch movies and stream music etc in the evenings.
