The appartment is really nice and clean, you are near a little place with good restaurant and bar, in the a beatiful area Alfama.
From the appartment, you are near of all the transport , Metro, Tram 28, Tuk-Tuk.., and of course you are near the Castel with a lot of viewpoint of Lisbon.
If you want to visit Lisbon I will recommend this appartement !
