We had a great time in Lisbon with the kids.
We were firsthand welcomed by Ana with warmth and smile.
Ana's place is great, very well located, in a sort of a private street, very quiet, with a nice view of the city from the living room and bedrooms. A grocery shop almost downstairs as well as an hotel where you can have breakfast if don't want to cope with logistics.
From the flat you can swiftly reach Baixa with an elevador exiting at the end of the street, or Graça and Alfama.
We'll definitely recommend Ana, her flat and Lisboa :-)
