Carmos is a super nice host, always ready to help and very professional.
The apartment is amazing, location better is impossible for those that wants to meet the hearth of Lisbon. Near of Alfama and baixa de Lisbon and great to climb up to the beautiful viewpoints of Lisbon Alfacinha.
I recommend people to use a electric bike if want to ride around the area. It is much faster easier and enjoyable free without guides and lines.
