Me and my family had a wonderful stay at Maria's flat - the location is very good, just a view steps from the Campo Clara with wonderful cafes and the famous flea market of the thieves as well as the Alfama with all its Miradoros and small alley ways. The flat has a fantastic view towards the river with ever changing activities of arriving and departing cruise ships (although I detest them, it was fascinating to watch).
The flat has everything one can need during the holiday and is in good shape - we felt very much at home. The house is old, with a narrow staircase but this adds to the charm. Maria was a perfect host, very welcoming and always accommodating (e.g. check-in and out). She had some very helpful recommendations (restaurants) which added to our wonderful experiences. I can only recommend this accommodation - we were very sad to leave!
