Me and two friends stayed at Vilma's appartment for just over a week in August and had the most lovely stay. The appartment is charming and well equiped and the location is just perfect, so central. On the little square next to the appartment there is a kiosk where you can get your morning coffee or a nice port after a day in the city/beach.
The appartment is right in the old centre of Lisbon so almost everything you want to go and visit is in walking distance.
Because Vilma was not in Lisbon to welcome us herself we had some help from Nuno how works at the gin house next door, he was very nice and provided us with useful tips about Lisbon! Altough Vilma wasn't there in person we had contact via text and she would always respond promptly.
