The Chiado Studio IV is perfect in every way. It is as beautiful as shown in the pictures; clean, and well-equipped. From the apartment, it is only a few minutes downhill walk to the Rossio square, the Comercio Riverside square, and other historical attractions. The Santa Justa Elevator is only a few steps away and the famous Sao Roque Church can be reached in just a few minutes. There is a Starbucks in a nearby mall, an organic supermarket opposite, and there are numerous nice restaurants in the surrounding area.
The "Chiado Studio Team" was very gracious and quick in responding to emails. I was extremely satisfied with my stay, and would certainly recommend this apartment to anyone traveling in Lisbon.
