We spend 5 days in Diogo´s appartment and it was amazing. It is situated directly at the picturesque Praca Luis de Camoes in the center of the Bairro Alto. It takes 1 minute by walk to the metro station Baixa-Chiado and a 10 minutes walk to the final stop of the airport bus at Cais do Sodré just straight ahead Rua do Alecrim or Rua das Flores We never met Diogo but his correspondence by email was very service minded. His partner Doris did the Check In and was a very friendly and helpful person. The stylish apartment has a living room and a bed room overlooking Rua das Flores with a side view to Praca Luis de Camoes. Due to high ceilings the apartment felt very spacious. The bed was fantastic and comfortable. The apartment was very clean and kitchen and bathroom had a view to the huge and modern staircase of the house. The windows were really sound approved. We closed the window in the bed room and had the window in the living room a bit open to get fresh air. The noise was not really a problem. Praca Luis de Camoes is a buzzling place with a lot of cafés , traffic and trams and even a lot of excellent street musicians and performers. The square gets quite quiet around midnight but the problem might be the masses of young party people switching after midnight from the restaurants and bars in Bairro Alto to the late open bar district in Cais do Sodré screaming and shouting and passing by the apartment through Rua das Flores. But you live in the heart of a lively city and due to the sound approved windows it never was a real problem. We would come back to this apartment every time. Obrigado Diogo and Doris!
