The flat was really easy to find, a short walk from the metro station and easy to get to from the airport. Once from the airport we walked everywhere in the city including Cais de Sodre for the train to the beach. The main city was reachable in 5-10 mins on foot and train station took about 25 mins (I imagine getting the metro would be quick and easy.)
The flat itself is small and cute, it is well designed and is ideal for a few days away, it has a large cupboard with a hanging rail although it would benefit from some additional storage space (drawers for underwear etc) flat is clean, had an excellent hair dryer, iron and some hand soap and shower gel.
The flat does not have air conditioning, it does have a large room fan which was adequate in September.
