Oscar's was very clean, safe, a great location. Walk down the street a little and you're at Praça da Figueira, which is a central location. It's close to sights like Praça do Comércio and metro or bus stops that can get you anywhere you wish to go (it's also a short walk to the train station which was great for taking us to Sintra for a day). It was a great airbnb, Oscar was very kind and helpful. He had a bottle of wine for us, a wonderful breakfast recommendation, help with the metro, etc. If we ever went back we'd definitely stay there again and would recommend it to others.
