I am absolutely in love with this hostel. It is the only A&O I have stayed in, but now I am certain if I travel through Germany I will book my stay at A&O. The staff are all incredibly friendly and helpful, if you have some sort of issue they will do all they can to help, and if you are just wondering what to do that night, they are always full of suggestions and recommendations. Though, to have a good time, you do not really need to go far, since "Bricks Bar", (the pub in the basement) is a wonderful place to spend the evening having drinks. The barmen are all really fun, joining you with your A-Bomb at midnight and suggesting what clubs are the good ones to go.
The staff are very multicultural: from all over the world, including America, Canada, UK, Czech, Slovakia, Greece, Morocco, Ukraine, Isreal etc. They are very welcoming, happy to have the guests feel right at home.
I really like the neighborhood where it is located. It is right across the street from Vystaviste Palace and Stromovka park (one of the largest parks in Prague. Also close to Letna, which is a really nice area to spend an afternoon stroll. Though, if you go in the direction towards Holesovice Station, it may be a bit shady area. Also, it seems that in Prague 7, people don't pick up their dog's poop, so watch out where you step and don't be too distracted by the wonderful historic buildings, or you may find something not too pleasant on the bottom of your shoes.
But, all in all, this is one of the best places I have stayed at, and I recommend it to anyone and everyone!
