Great flat at the Rossio metro station on Lingha Verde. Very convenient if you want to travel to Sintra and Cascais.
Neighbourhood is nice too. With plenty of good (if not great) restaurants.
We don’t really hear the outside noise except maybe the bell from the nearest church.
There’s a small balcony with a great view on the street where line 28 tram drives by (nice to take good pictures).
María is very nice and helpful. We didn’t have any trouble to self check in.
