The apartment is situated in a quite area just near the metro station and a big mall. The center is easily accessed and if you come to the Dom Luís I Bridge, you'll get an amazing view.
The apartment itself is very cozy and clean, there is everything you need there.
Antonio is a very nice host: we've had a late flight and intervals between metro trains are rather long at night, but he kindly waited for us at that time. Also after checkout he politely let us leave our bags to have a walk before evening train.
Totally recommend!
