I'd dream of having a little place of this myself in Lisbon...if Joana ever wants to sell, I'd move in a heartbeat. As I explored the area, I discovered it was so near to the city, only about 20 mins walk to most places, either into the city or down towards the river and Alcantara. Everything I needed was there. It was great to open the windows and listen to the blackbird carolling on the rooftop opposite. Yes, you'll hear locals laughing at the bar on the corner during the day , but it's really quiet at night, and I found it very safe to walk back to.
A lovely experience.
