Super location if you want to be in the historical center (a bit touristy now but very central). The closest you can be from the Lisbon night. The appartement is huge and can easily welcome 6 people, be aware that there is just one bathroom you'll have to take turns. The kitchen has everything you need. The appartement looks nice in general but if you look closer it needs some little arrangements.
Not a very fan of the "hôtel" kinda of thing treatment. (Pay for the locker, please tell us if you want to PAY for a pick up at the airport, tell us if you want to PAY for a Tour...etc)
