I've been all over Bucharest and this is most certainly the best hostel in the city. Very nice staff, cool terrace and kitchen, fast internet. Right by old center and all the bars. Nothing bad about the place. You might meet some strange tourists from all over the world but that's part of the fun of staying in a hostel in a big city.
Friendly cute girl at reception, after check in they left me alone which is nice. Wifi is smoking fast, I was able to download a 1 GB file in about 20 seconds. Cheap and right in the middle of centru vechi. Showers are weird, takes some finesse to get a good pressure and temperature. A compromise that comes with being in the middle of the party, you are surrounded by clubs that blast music all night and drunk people are screaming outside along with it. Security is a little questionable, use the provided lockers!
