Maria's apartment is very well adapted for families of 5-6 members.
It is elegant decorated, it has every thing is needed for a vacation stay.
There are small stores close to the apartment, just round the corner. There is access to walk-able distance to public transportation. We bought service for Lisbon public transportation which even took us to Sintra, per about 12 Euros a day.
Maria was very helpful giving us directions, and indications to take advantage of our stay in Lisbon. She even help us finding a taxi service to take us to Fatima and airport in the same day.
We had a very good experience at her apartment.
