The host cancelled our reservation due to a technical problem.
We had to found another accommodation and it was not easy: we lost 5 hours of our day that we could use to visit and enjoy Lisbon, that the worst thing. Anyway we had a full refund.
Despite that the apartment is really nice and it’s in a perfect location in the centre of Lisbon, perfect for 4 friends/ 2 couples. Hope they can fix everything.
