Nice small flat. It’s clean, has very comfortable beds and is fine for up to four persons if you don’t plan to spend much time in the flat (which you shouldn’t, there is some much to see!). It’s in the heart of Lisbon, so almost everything’s in walking distance, but on the other side during our stay (Friday/ Saturday) it was very noisy until very late (3/4/5 am), so if you don’t go out and prefer going to sleep early definitely bring your earplugs ;)
