It’s a cute little studio apartment in the heart of the city. I would recommend this place as it is in a great location. The plus in summer was the fact that it is air-conditioned which I think many apartments in Lisbon are not.
The hosts are very responsive too. Overall we had a good stay.
Since it is on a busy road, ear plugs are needed. However this is natural as in every city center it is always busy.
The only change I would make in this apartment is the the bed. The bed is a big minus as it shakes on even a slight move and is too small for 2 people.
