I was staying at Claudio's apartment with my partner for 5 days and we were very pleased with everything. The location was just perfect - it's super close to some of the nicest spots of Lisbon such as Miradouro de São Pedro de Alcântara, Bairro Alto, Avenida da Liberdade, and the botanical garden, and at the same time the street is not noisy at all. The apartment is very well equipped, there's everything you'll need during your stay and Claudio is just the nicest host you could ask for, so we definitely recommend staying at his place :)
