A truly wonderful apartment. I was there by myself and it was perfect and spacious. You are staying on a popular street so it does get noisy at night. But I closed the hallway door and the bedroom door and slept through the night. There isn't much natural light except through the front door but I was hardly at the apartment except end of day.
It was a delight to walk out everyday to have a front row street to the famous street and funicular. The only catch is that the apartment is on a steep street (i.e. the burden of pulling luggage uphill :) ). But be warned, steep streets are all over Portugal so you are just getting a good butt workout.
