Sílvia's apartment was great! She managed to host me and my mom with a few days notice. The apartment looks like it has been renovated and furnished not too long ago. Very clean and comfy. The area is amazing! Yes, you have to hike a bit to get to the apartment, but it's close to Bairro Alto's supermarkets and restaurants. The main shopping street is also close by. Will definitely stay at Sílvia's again the next time I visit Lisbon.
