This was the perfect place to stay in Lisboa.
It was close to the sights, and an easy walk to the train/metro/tram. Plenty of restaurants- local and touristy in every direction, but generally quiet location of the apartment. People passing through occasionally but the nights for sleeping were peaceful.
I was traveling alone and felt very safe! Diana was also very communicative and accommodating!
Small bathroom but manageable. Highly recommend :) you will fall in love.
