Our stay in Marias AirBnB was really nice! Mostly we liked the garden and the beach, which is only 10 minutes by walking away. It was really quiet and we were able to relaxe a lot. Sao Pedro do Estoril is a small town, but the connection by train to Cascais, Carcavelos and Lissabon is really good.
Eventhough we couldn't meet Maria, we were happy to get to know Carmen, the housekeeper, who is really helpful and nice.
If you want to calm down and enjoy life, Marias AirBnB is awesome.
