Our stay in Orange 3 House was very good.
The top floor apartment is clean and functional and right in the center of Chiado. It overlooks a small alley with cute orange trees and is therefore less exposed to street noise (as is often the case in the center). It looks slightly bigger on the pictures than in reality but overall it's a very good apartment for a short stay in Lisbon. Beware however of the shower which has a small hot water tank (but in my experience, this is the case of almost all the apartments in Lisbon).
Our host igor was adorable and extremely accommodating. Igor is not only a host but really a guide for the travelers. He takes his role very seriously and had great advice on places to visit, restaurants, activities, etc. He made this stay wonderful.
Thanks again Igor!
