Our stay at Carlas house was great. Carla and her friends are great hosts and often offered us additional help (free rides to the metro or train station and nice insider tips for lisbon)
The accomodation was about 15 minutes by car/ bus to the metro-station potinha, so its a 30 minuten trip to the city centre of lisbon.
The rooms itself were very spacious, clean and equiped with everything you need!
