We had a blast at their appartement in Lisbon! Sergio was very welcoming upon our arrival and showed as everything. We are both deaf, so we had to read his lips, but it was no problem. We didn't even had to write something down :) The appartement is located within a quick walking distance (slightly up the hill) from metrostation baixo chiado and easy to find. It was a perfect start to our trips every day. Sara and Sergio also organized a taxi for us, because we had to leave very early on monday morning. Everything went well!
