The apartment was great for our stay in Lisbon. You have everything you need in the direct neighborhood (supermarket, metro). You need around 15 to 20 min to get to the old town by public transportation. For us it was perfect because we also visited Sintra, Cascais and Cabo da roca.
And a big thank you to Gonçalo, who was our contact person during our stay. He gave us a lot of great tips and always answered very fast.
