I stayed at Filipe's place for two nights while traveling solo in Lisbon. The flat is in a super cute neighborhood with small stone streets and old houses, but very close to Ave Liberdade with all the bigger shops and things. Loved hanging out on the patio in the hammock. Pleasant stay, easy check in and out. Just be aware that the street is very small and the address a bit hard for taxis and Uber drivers to find (bigger cars don't fit down the road) so I just walked down to Ave Liberdade to catch rides which was easier.
