We stayed for 3 nights with a family with 2 kids, and it was a perfect stay for us. Eveything was very clean and the whole equipment fits all what you need for a stay like this. The apartment is very centrally located and almost all can be reached in walking distance. Communication as well as check in was completely uncomplicated and we got good tips and recommendations for super market, restaurants, etc. just around the corner. So all in all a highly recommendable location in a very central spot of Lisbon.
