Our group (two couples, one in their 60s and one in their 30s) stayed at this property for only one night (our last in Portugal). The house is at a great location (close to the monastery, museum of coches, pastéis de Belém, public transportation, and many restaurants), was very clean, quiet, well-equipped, and we all felt safe. We got lucky and found street (parallel) parking almost in front of the house (and then didn't use the car for the rest of the day), but having stayed on the same street before (different property) I can tell you that parking in that area is not super easy. The host did her best to make the sofa bed comfortable but it was still quite uncomfortable for two medium-sized adults. Perhaps it's more adequate for children or a small adult sleeping alone. Overall it was a good stay and if I went back to Lisbon alone or with my partner I would stay there again.
