We (three friends) stayed in the apartment for four nights. When we arrived, everything was really clean and welcoming. We were welcomed by Maria’s husband, who did the check-in for the first time. He was really nice and explained everything very well.
The apartment is close to the train station, which makes it very easy to take the train to other places. Of course, this means that you can hear the trains in the apartment, but if you close the windows this isn’t a big deal.
Saō Pedro de Estoril isn’t as busy as Estoril centre, but everything you need is in walking distance (beach, supermarket, bakery, restaurants ...).
We had a great time!
