Both my mom and I had a great experience staying at Maria's house. Her son António checked us in and was a very friendly and attentive host.
The house was sparkling clean and extremely cosy. We stayed in wintertime and still made use of the patio every day to eat our breakfasts.
It is very easy to explore Lisboa from where the house is located and in only 2 minutes walkingdistance there is little grocerystore, pharmacy, cosy pubs...AND Vizza where they offer great vegan pizza!
I would recommend this place to everyone visiting the beautiful Lisboa.
