Pros:
Flávio’s place is centrally located (20 minutes walk until Rossio train station).
There are many restaurants and groceries nearby.
The beds were comfortable.
Cons:
All six rooms in the apartment can be rented individually, like a hostel. At night, the noise from closing and opening doors from the other rooms and people talking in the kitchen could be easily heard from our room.
The room we stayed in was quite small, not enough space for 3 people + luggage. There was no ventilation, it got very hot with 3 people in the room, even with the window open (the window was facing a wall of the opposite building, at less than 1 meter away). There was a small fridge in the room right next to the double bed, and because of the noise coming from it, it was difficult to sleep at night.
There was a construction work going on around the listing and the work started very early in the morning. The noise coming from the construction work was another problem for good sleep.
