I've been frequenting this place for almost a year and I have to admit that I'm astonished. The hotel itself is in the suburban area of Niš (just some 10-15 minutes drive from the city center), but that is no problem at all, since the taxi is pretty cheap. The variety of the rooms goes to a pretty big extent and all of them will absolutely charm you with their comfort. Even though the hotel is not one one of those places that aspire to be vintage and rustic for the sake of being vintage and rustic and it's going along the line of the more modern accommodation establishments, I have to admit that it has a soul.
There's a lounge bar, lobby/chill out zone, the restaurant (serving breakfast) is down right amazing. Every time I stayed here (and it's been 5-6 times in the last 12 months), I was positively overwhelmed with coziness of it. The staff is also amazingly pleasant and complaisant and, if I may add, very amicable.
Whether you are staying in Niš for longer or just passing by and you need a place, really, look no further. Like the city itself, the 018 In Hotel is very near to the E-75 Highway (leading to Bulgaria and Greece, etc.) so I would really recommend it if you're travelling through Serbia to stop there and go check Niš out why not.
This place just feels like home - the service is impeccable, the rooms are immaculately clean and the overall coziness of it will make your day(s). Also, the prices are way too generous so no need to worry about that either.
My warmest recommendations!
