The apartment is located really central and close to metro (Martim Moniz) and within walking distance to many of Lisbon's top sights, inlcuding the Sao Jorge castle and the popular tram 28. We were really happy to check in earlier, and the Portuguese lady in care of the the apartment was very friendly. The apartment is perfect for couples and has anything you would need to cook breakfast or basic dinner. The place might be challenging to find, but we managed perfectly using Google Maps. All in all we were very happy to have Sergio's apartment as base during our stay in Lisbon, and we warmly recommend it.
