Maria is a very friendly host. On the first day she invite me to have a beer on the "miradoro monte agudo" and that is an amazing welcome. You really can see all Lisbon from there.
The apartment is extremely comfortable, very tidy and nicely decorated.
The subway is really close and easy to get to downtown, and the best is the 28 tramway is also very close.
The only regret it was to short time :-) but I'll be back for sure.
