I stayed at Alexis's place with my partner and two kids. It was very comfortable with good quality furnishings, some cool artwork and thoughtful amenities. It's not in the tourist centre of Lisbon but rather in more of a residential neighborhood and fairly close to newer cultural attractions such as LX Factory and MAAT (and only 15 minutes to the airport by cab). Alexis clearly takes pride in hosting, he was proactive and made sure we had everything we needed.
