Chiho and Nuno are wonderful hosts. Chiho met me and my Mother at the airport and helped us check in, giving us information along the way - she also supplied links to various museums and concerts I'd asked for.
The apartment is in the heart of the city and as close as can be for Tram 28, Rossio station and Tram 15 to Belem - it really is brilliant.
A lift is to be installed reasonably soon (it's quite a lot of stairs) which would make this apartment the only place to stay in Lisbon!
