João's studio apartment was just great for me and my girlfriend Anna's stay in Lisbon. The place is beautiful and cozy (and spotless), the location is great (close to restaurants, subway, and with grocers and bakers around the corner), and nice and quiet, too. The size is pretty much perfect for a couple—a bedroom (with a small table for having breakfast), a kitchenette (even stocked with some snacks, tea, etc) and a super-fresh bathroom.
João was an amazing host—he met us downstairs when we arrived and showed us around the apartment. He was very responsive and communicative both before and during our stay, providing very clear and useful information—we felt like we were in great hands.
