Pedro (and his wife) was very nice and gentle with us: he helped us with our luggage and welcomed us in a very kind way. He also explained what to see and do in Alfama and how to use the house furniture, he let us use everything we need.
The accommodation was colourful, clean, and with enough space for two people. The position was perfect and near to the station of Santa Apolonia, but also to the beautiful and characteristic streets of the neighbourhood.
I strongly suggest that you meet Pedro and stay in his flat!
