Although it was a quick stay, everybody was very friendly and helpful to us and I would definetly visit pop art one more time! The place is amazing, full of colors! You should check it out if you are looking for something different during your stay!
Finally, the hostel is on a perfect spot, right next to the main bus station and the main railway station and near (5 min walk) to the center. There's also a bus to the airport 5mins away from the hostel!
Pop Art hostel was in a great location,very close to all Belgrade attractions, bus station and walking distance from markets and shops. It was also convenient to have full kitchen, wifi and TV in the Hostel. Room and bathroom was very clean and nicely kept. Hostel staff was very helpful and provided us with a lot of information about the city and Serbia itself. Since its an art hostel and obviousely people who stay there and supervise it are young people, it was noisy up to late at night in the public area, and you could be easily desturbed. Our stay was spoiled by the incident at check out, since there was a misunderstanding between host, airbinb and me as a guest. It was professionally solved by airbnb, which i can't say about the host who got very emotional.
