I was in this flat few days in September. André was very nice and very helpful, he also helped me with my super-heavy luggage. The apartment is really nice, a bit detached from the touristic city centre but very close to the Alfama, the big station of Santa Apolonia and the stop of tram 28. The place is pretty small, especially the bathroom, but it is more than enough for staying in Lisboa some days and visit the city.
I would definitely recommend this place! Thanks to André!
