We loved the common area, where it was really easy to meet new people. Also the staff girls were super nice and helpful and gave us tips on where to go and helped us booking a bus for our next stop of our journey. Usually they have free activities every day (like going to the night market,..), but unfortunately there was no event happening when we were there. Yet they still organised a private one after we asked them :)
The room (we stayed in a private) was super clean, cozy and had a nice A/C and a fridge. Even though the hostel was pretty full and there is a rooftop bar with live music, it was still really quite in the room. They even cleaned our room every day and gave us new towels.
Breakfast (fruits, cereals and toast) free and available until noon.
The location is perfect to hop on a taxi boat to explore the city and also just 5min walk to khao san road.
Wifi worked perfectly fine, plus they have a PC in the common area free to use.
Reception was open 24/7.
All in all probably the best hostel in bangkok.
