Sofia' place is beautiful. Full of lovingly curated detail. Her apartment is a peaceful artistic retreat that welcomes and encourages you to explore and dive into all of the delights of Lisbon and Portugal.
The area of Belem is beautiful and the apartment is within walking distance of many wonderful sights and some excellent restaurants. Belem is a little away from the downtown city center but well served by public transport and a Bolt will have you into the city center in no time.
If you want a peaceful retreat to enjoy Lisbon, Sofia's place is highly recommended.
