Recently stayed at four points by Sheraton Matosinhos. The building was in good condition; our room was small, but clean and well-appointed.
Most of the staff were friendly, but the receptionist who assisted us with check-in was impatient and rude, and made us feel not welcomed.
On the first evening, the shower flooded the bathroom and the bedroom within 2 minutes. The staff kindly delivered many towels, but we had to use them ourselves to gather the water and dry the floors.
They were unable to immediately move us to a different room.
We would expect a full refund for the first night of our stay, but the manager said most they can offer is 25% off for each night of our stay (2 nights total).
Not sure if we will stay there again.
