This place is great! Awesome location right next to two subway lines, shops, cafes, and rossio square market. The neighborhood is very fun and a good location for exploring all of Lisbon and Portugal.
The only thing people should be aware of is the bathroom. The toilet is separate from the shower and sink and is basically just a closet with a toilet in it. If you are traveling solo, it’s no problem. If you are traveling with someone, however, there is very little privacy when conducting business. It has a door but it leaves little to the imagination. Make sure you are comfortable enough with your traveling partner to live like that.
Otherwise, the hosts are excellent, apartment is clean and well managed, and the AC works great! Would definitely stay here again!
