I stayed 4 nights at Amelie and Marinho, in rua de Sao Lourenco 19, in the Mouraria, with my husband and teenage daughter. Everything worked out just fine. Communication was smooth and prompt from the start. They let us check in early, we picked the key from the neighbour and settled in a spacious, light-filled apartment. The apartment has two bedrooms, and a living room-kitchen: it never felt cramped, and could easily host a family of four, although the double bed is a bit small. The kitchen has all the appliances you might need: kettle, microwave, coffee machine, a mini-fridge and mini-stove. Complimentary coffee and tea was there too! There was plenty of towels for everyone. The shower in the bathroom was excellent; the place is completely air-conditioned. Wi-fi just fine. The apartment is very well located for a visit to all of Lisbon's main sites: St. George castle is really close and we walked everywhere. But the bus-station Martin-Moniz is also round the corner. The area has lots of typical restaurants and our hosts suggested Zé dos Cornos, just below our place: we loved it!
We never met our hosts, but as I said, they replied promptly and kindly to my messages. It is an ideal solution for a short trip to Lisbon and I strongly recommend it.
