I booked this apartment on behalf of my parents for their extended stay in Lisbon: The location is really convenient to all major attractions and at the same time was in a really quiet & charming part of town. The apartment had great light and view of Lisbon's skyline. It also had all the necessary amenities for a comfortable extended stay.
The only thing to note for future travelers who may be older or have large suitcases, the stairs are quite steep and narrow.
