Mariana was very kind and fast in the answers. Miguel (the driver she recommended), also was very gentil and handy, specially for the first time in Lisbon. The apartment was great: Clean, very big for two bedrooms, very high ceiling, refurbished in a hystoric building. Towels and bed sheets were all White, new, soft and very clean.
Also, parking lot available at the underground of the building, very conveniente if you are driving. And finally the location could not be better. It was a walking distance for evething (Rossio Square, Bairro Alto, Chiado Market, Chiado Square, in the middle of the most fancy area.
I definetively recommend Ana & Mariana´s apartment, specially for families such as ours (four people).
