We had a great stay at Antonio's amazing duplex apartment, with an amazing roof terrace.
The location is splendid! If you're a light sleeper bring earplugs (or use the ones provided by António), on the weekend the party is on the streets. It's great to join the locals for a drink outside, there are many bars and amazing restaurants just within a stone's throw. If you're not up for a wild night the roof terrace invites you for a more quiet relaxing session. In the background, you'll hear the buzz of the streets, but you can easily talk, listen to music, without bothering the neighbors.
António is a great host, even though our arrival was very late in the evening, he made sure to show us around and do a personal check-in, very much appreciated. In the end, he allowed storing our bags for a couple of hours, so that we could get the last breaths of air of Lisbon without carrying them relentlessly around.
