I had the incredible good fortune to stay in Chiado Studio II and Chiado Studio III on my first trip to Lisbon in July. It was my first airbnb experience...and now fear I've been spoiled! Unable to book one apt. for 5 consecutive nights (they're extremely popular, and with very good reason), so I spent 3 nights in one, then moved one door down the hall to the other. I can't say enough good things or rate the experience any higher -- the design and use of space is impeccable, each super clean with fantastic beds and bedding, gorgeous marble baths with large soft bath sheets, fresh oranges were left by the gracious hosts in a bowl to be juiced in the morning, and wine in the evening (or afternoon!) and delicious natas for a snack. The views are ridiculous/breathtaking, and the cross breezes in Chiado Studio III (a corner unit) amazing. Antonio, Gancalo and Catarina were a pleasure from the first reservation confirmation until the final goodbye, and were so accommodating with my "move" and with all communication and suggestions. The area is the best...quiet, peaceful and on a beautiful, tranquil square with a typical kiosk and a few cafes, where oddly enough i ran into the one person I know who lives in Lisbon --- the square is one of his favorite spots in the city. Amazing bakeries and restaurants and shopping all steps away from the architecturally significant building. My tip -- reserve now!
