It's a nice place to stay for a single person or couple an perfect base to explore Lisbon. The area where the apartment is located is amazing with some real nice cafés around the corner. Also the communication with the host was super easy and friendly. We arrived a bit too early at the place but it was no problem to drop our luggage. It was just that the bathroom door could not be closed completely, which can lead to unpleasant situations. But not a dramatic problem at all.
I can strongly recommend Ana's accommodation!
