We travelled with a child and paid extra for that, even though during the booking it clearly said for three people.
Then it turned out that there was a nightclub at the same building. The whole room was rumbling from the noise, no one from the hotel to help us. They should have been stopping the music at 3, but did not.
None of us could sleep. The club is open every day, except Mondays.
The hotel staff was unhelpful, the whole situation solved only because Hotels.com helped us and we booked a new hotel in Kolonaki area.
