We enjoyed Mario's apartment very much. It is very nicely renovated and spotlessly clean. Lots of natural light in the morning which makes you enjoy the start of the day. Also the building looks very authentic - Portuguese tiles on the front and azulejos inside the main lobby.
Perfect distance to the tourists spots - close enough for an enjoyable walk, but not too close to be crowed or noisy.
We had a great stay! Definitely recommend it!
