Good position in Kalambaka, free parking, good WI-FI. Only the young lady at the Reception Desk was a professional, good English speaking and very helpful.
Her colleague - an impertinent guy - suggested us to book rooms at Hilton, when we asked for the remote control of the TV set, which did not have even the button to turn it on and also asked about the refrigerator (as we had paid the price for a room with fridge), no glasses, only 1 chair, 1 night table in a triple room, coat hangers made of rusty wire, cobwebs hanging from the ceiling, stinking room. A/C looking as if it had been in fire some time before. No courtain at the shower cabin, old rusty taps, dirty glass for the tooth brush, no hair dryer, 2 (instead of 3) dirty chairs, no table on the balcony. Poor breakfast. NOT A 3 STARS HOTEL, NOT EVEN ECONOMIC CLASS! A shame among the greek hotels (all the others hotels I have stayed in Greece were very good). Odyseeon Hotel is the worst experience we have ever lived in a hotel! It was the nightmare of our holiday. A piece of advice: Never go to Odysseon Hotel! (also taking into account the behaviour of the man in the Reception who lives from the money the tourists pay!). There are many other good hotels in Kalambaka.

Plus
- Excellent location, at the beginning of the road to the monasteries and walking distance to the center of Meteora.
- Helpful staff
- Some rooms have nice views.
Average value for money
Average breakfast
Minus
- Some of the smallest rooms I ever stayed
- Weird bathroom with dubious tap water
- Tiny TV set
If you intend to stay only one or two nights this is not a bad choice.

Good value for money. Hotel Odysseon is much closer to the cliffs/rocks/monasteries than most other options, although it is not as close to the bus stop at the main square. It is also close to the village of Kastraki.

The buffet breakfast is pretty decent -- scrambled eggs, ham, cheese, croissants, jam, yogurt, honey (for the yogurt), fruit, coffee/tea/milk, orange juice, and cereal.

The staff was also very helpful with travel information and spoke good English.

Main drawback is that there were flies -- maybe 5 or 6 of them -- trapped in my room when I checked in. It was a hassle trying to get rid of them.

....because they look better than what you'll get!
We book 2 garden and mountain view rooms. One of the rooms has very small, had no frige, no functioning AC, and more of a tree view, than mountain. The bathroom is quite ugly, old tiles, no curtain, no place to put your shower gel. Although clean, the sheet had 2 nut sized holes on it. There were no tables on the balcony, but 2 old, ugly chairs and an army of ants. The yellow garden chairs were torn apart. A lot of noise on the hallway, you could hear every door closing. The staff was really helpful. We stayed there for only one night, so I wouldn't recommend it for a longer stay.
