Diogo and Carlota's place is in an incredible location and the place itself is really nice, and perfectly sized for 3 college aged people!
They were super responsive and provided lots of great recommendations for exploring the city. They were even nice enough to set up a taxi for us at 6 in the morning the day that we left. Overall we had an awesome experience at their place and would highly recommend it to anyone looking for a great place to stay in Lisbon!
