We only spent two days in Antalya.
The hotel is well-located in Kaleiçi, as you have a beach at less than 5 minutes, many shops, pubs and restaurants all around. There is also Karaalioglu Park at 2 minutes, it is so beautiful and peaceful to have a walk there.
The hotel is clean and the room are very decent for the price you put in. Also, the staff of Özmen Pansiyon are all very kind, smiling, helpful and always there to give you advice about where to go in the city.
From the terrace, you can see the sea and the mountains that surrounding it, that's amazing. The breakfast is very mixed, so you have a large choice of things to eat (and alsothe typical Türkish Tea!)
I really recommend you this hotel whatever the time you want to spend in Antalya, the hotel is as nice as its staff.
