I liked this apartment much. It's located in the very old historical building, but is modernly renovated in Scandinavian style (everything is white, clean, like in the best IKEA catalogs), so it reaches both goals, that are important for traveller:
- gives you the vibe of heart of the city (old building, tiny street, just like locals live)
- has all the necessary amenities and level of comfort (fully equipped kitchen, bathroom, heating, window blinders, cosy bed)
So it's perfect to experience the city in good living conditions.
The neighbourhood is maybe the safest in Lisbon, you can walk around any time of day and feel completely safe.
