We had a great experience at Maria & Rita's apartment. The place is exactly as shown in the photos and the host was very helpful, answering every question quickly whenever needed.

Pros
Location in the heart of Chiado in a quiet street
Comfortable apartment, with a huge closet and all the essential amenities

Cons
Climbing the stairs with heavy luggage can be exhausting
We felt the absence of AC (even though we were provided with two fans) - Lisbon can be very hot in the summer

Thanks Maria and Rita for everything, we certainly recommend the apartment.
