J. Mario's place is in the perfect location to visit the most interesting and characteristic parts of Lisbon without getting stuck in the over-touristy centre. It is a couple of hundred meters from the metro (Rato - yellow line), so very simple to reach from everywhere in Lisbon and indeed the airport. You can walk to the centre in 15 mins, to Belem in 20-25, and in every direction there is something nice to see, e.g. the Mercado do Campo de Ourique where you can buy or savour all the delicious Portuguese specialities, especially fish! I definitely recommend this apartment, very comfortable for a couple or even three people for a weekend or a week, plenty of space and equipped with everything to be able to cook and eat at home, chill out and not always have to go out to eat or whatever.. nice view over the houses at the back and a church tower, just great!
