The loft is truly amazing, once you walk in you immediately realise that there is some kind of history and of lived past in the building and inside the house. Everything is decorated in an artistic way, but still very functional. No complaint for noises, isolation is very good and you're not in the middle of chaos, though staying in the perfect spot for everything (walking around, nightlife, restaurants, etc), being in Chiado.
I do recommend "Sea Me" restaurant (great fish and sushi) and, for pizza lovers, "Mezzogiorno", both walking distance.
We were there with our 2yrs-old daughter, and Margarida prepared everything for her. That was unexpectedly nice. In general Margarida is a fantastic host, very caring and easy to communicate with.
