Adriana's place is very conveniently located accross from one of the main train and metro stations in Lisboa (lisboa - st. Apolonia. If you arrive by train is just perfect. Also metro runs until late evening so it'should ideal to go and visit other part of the city at anytime.
The district of Alfama is just a few minutes walk away. Very convenient.
The flat has a good kitchen space and bathroom. There were other guest but we never felt crammed at all.
Adriana is lovely and caring and gave us lots of tips. Just a pleasure to stay with her.
