I stayed at Maria's place in Lisbon for 3 nights and had an amazing time. It is centrally located, safe, and walking distance from many of the important neighborhoods in Lisbon. Plenty of great coffee shops and restaurants nearby as well. The apartment itself was comfortable, though I imagine for someone very tall that might not be the case. Some of the ceilings aren't particularly high. For me it was not a problem at all. It has two nice balconies with good views of Lisbon. Overall, very happy about my stay!
