I loved this place cuz it has everything for a comfy stay when you want to explore Lisbon or just stay in chillin.
Very easy to check in. Place is on a street which is not loud/busy but close to everything you need. Restaurants, shops, bus stops, subway, mercado everything just step away.
Arroios is definitely a place to start to check out Lisbon. It feels more as a city than other parts.
