Ricardo was incredibly perfect: He communicated helpful, early and realiable always wenn it was needed. He received us charmly (though our nightflight arrived later than planned) at night, and he gave us local tips. The flat was very nice, clean, and really in the Center of the town.
Only little tip: There ist only one room with a double bed, and one with a single. The second double bed is in the living room. But it's a Detail.
We will - if possible - book again with ricardo, next time we are in Lissabon. Thanks, Ricardo! :-)
