We enjoyed our week in Estoril very much, although we were not so lucky with the weather, as it was quite chilly. Therefore we couldn´t use the very inviting pool, but instead the heating for some days.. ;)
We were there with our 1 1/2 year old son, and visited Lisbon, Estoril and Cascais without car, all of it no Problem. Only the stairs to the 2nd floor were VERY inviting to our Baby, so we had to watch him carefully. But as Margarida had provided a Baby bed and seat, we were well equipped.
Tip: Try a Breakfast "Biaritz" at the Cafe Saboia!
Margarida was very nice, helpful and everything went fine! Even when the (youngster) neighbours were having a little party late at night which woke up our kid, she delt with it.
So: highly recommended!
