Ana was very friendly and the location of the flat is amazing. It is very close to the centre, public transport and the Rossio, which makes it perfect to get around and out of Lisbon (recommend going to Sintra which is very straightforward from there). Getting to the flat from the airport is also easy by Metro.
The flat has everything you need and is a good size. We had a great time there. The neighbours dogs were a bit loud sometimes and the walls are a little thin, but Ana provided ear plugs in the flat.
