Well, first of all Rui, a nice guy, friendly, serious and simpatico, available all the time.
The apartment! Location wouldn’t be better.
If you follow the guides you will probably stay at Cidade Alta, Alfama, etc. Don’t do that. Lisbon was destroyed by an earthquake in 1755; there is nothing ancient there, only old builds, needing a pint, tourists and “tourist restaurants”.
This flat is near São Sebastião Metro station, main way to the airport and just a few steps from El Corte Ingles, the Lisbon shopping paradise. Located also near to the Pastelaria Versaille, in the Belle Époque stile and hart of New Lisbon life. Campo Pequeno and Laurentina Resturant, king of Bacalau!
The flat need some repairs, but they told me they are just about to do it.
So! Don’t miss the place.
