Me and my sister stayed in Lisbon for 5 days. The apartment is in good shape, but there wasn’t any soap, cooking oil or salt and pepper. The apartment is really high up under the roof, so keep that in mind. As other people already mentioned, the street down below is quite noisy, but we didn’t mind.
The check-in wasn’t complicated, but it’s wasn’t as comfortable, since we had to go to the office first, to pick-up the key. The staff was really nice though and you can keep your luggage there.
We liked the location of the apartment, it was really easy to get around. The apartment smelt really nice!
