We had great time at Antonio's, the flat's been just now nicely and smartly furbished, everything is new and has the real vibe of Lisboa.
The flat is in the basement, so be prepared for a bit less natural light - but if you spend your days scrolling around the city it will not cause any problem. One more thing to warn: the closenes of the neighbour door sounds like someone is entering your door, but no!:) I have to admit that the whole area is very safe, calm and friendly.
The Tram28 has a stop real close to make the travel easier, though Estrella is very charming to discover also on foot.
And our insider tip is to visit the "little sis" of Time out Market, Mercado Campo de Ouriqe, which is more local, easy going, and a bit friendlier priced.
All in all, recommended!!:)
