The positives:
We had a pleasant stay at Urban Colors in Thessaloniki. The location is very central, and the room was clean and comfortable. The hotel also provides information about parking options in advance, which is very helpful if you’re coming by car.
A small note:
There is no private parking at the hotel, so it’s worth planning ahead if you’re travelling by car.
I also accidentally booked an “internal” room. It had a window facing the corridor, which cannot be opened, so the room felt a little claustrophobic. We only stayed for one night, so it was absolutely fine for us, but I would keep this in mind if you’re planning a longer stay and prefer a room with a proper outside window.
One other small thing: the shower holders in the bathroom were a little loose and could use some maintenance.
Overall, a clean and very centrally located place, and we had a good stay.
