We spent 3 wonderful days at the apartment and we really enjoyed it. Catarina and Alexandre were very friendly and helpful - great hosts!
One highlight of the apartment is the balcony with the beautiful view over city and river. The apartment is quite compact but very clean, modern, and fully equipped. It is also very bright because of the large windows. The location is great, in the heart of Chiado, a nice area, and really close to metro and famous tram 28. Because of the central location it can be a little noisy at night, if your sleep is not very deep.
Everything was working well, including WiFi, and we had a nice and comfortable stay!
