It is very charm and comfortable flat. Clean and very good equipped. best place for staying for friends as well as for families. I highly recommend it for everybody visiting Lisbon. Apartment is located in the heart of the city and only few hundreds meters from Lisbon metro and other transportation. Helena is very helpful. She gave us some tips and useful advises. At the beginning she left us a small gift - bottle of local vine :)
The only disadvantage was unpleasant smell in one of the bathroom, which appeared once and then disappeared. However the building and place is quite old, and it has to have some secrets ;)
