Perfect stay, would highly recommend! We (myself, hubby and our 8month old) stayed for 3 nights. Ricky met us for check in and helped us park our car in the garage...where it definitely stayed until we left Lisbon as driving is pretty crazy as a foreigner! He was easy to communicate with, checked in on us, gave great local recommendations and there were many thoughtful welcome touches.
Apartment was spacious, clean, comfortable and well decorated. Location was perfect and central in alfama. The street quiets down in the evening, but regardless it is quiet with no street noise in the bedrooms.
As a side, if walking through alfama with a young child we highly recommend using a backpack or carrier. We used both daily and never opened our stroller in Lisbon.
