I stayed in the apartment the second time. I just can repeat my last review. The apartment is just around the corner of the metro station and a supermarket. By foot you can reach the city center in 10 minutes.
The location gives you the opportunity to discover Lisboa more easily because it has public transportation just across the street.
The apartment is nice and bright, with a beautiful balcony. The kitchen offers everything you need.
Gaspar is the best Host you can imagine and offers the best check-in I experienced so far (and I stay in Lisboa for more than 10 years and saw a lot of other locations!).
Short: 10 out of 10
Thanks again, Gaspar! Até próximo año :-)
