The hotel offers the best service at this price. I came with my boyfriend and we chose this hotel particularly because we they did not have a request to show marriage certificate (in the South East of Turkey it’s a big deal). We got a huge room. It was comfortable, clean, bathroom was also very nice. Air conditioner was working - which is important for Gaziantep with its hot weather.
The only one thing that can be a problem for tourists or foreigners - the place where the hotel is located. It’s actually a poor Syrian neighborhood and it can be dangerous in the evenings. However we never had any security issues there and it was convenient to walk to the city center, old bazaar and castle which are not far from the hotel.
I recommend staying in Buyuk Velic Hotel!
