Good: Carlos is a friendly host and very uncomplicated. The appartement has a very nice location and good looking furniture.
Bad: There is mould arround the windows and also on a few spots on the wall. The showerdoor is leaking so there is a lot water in the bathroom after showering. Worse is the mould inside the shower witch is kind of gross. These circumstances made showering unpleasant.
Overall the appartement is nice and is a good base to start activies arround Lissabon. But due to the mould-situation i wouldn’t book the appartement again.
