I came back for a second time because I remembered the hostel to be located very well, directly on the Old Street "Laojie" and with a great (tasty, affordable and nicely decorated) restaurant just opposite. The hostel offers daily rides (6:10am) to the Yellow Mountains "Huangshan" for 22 RMB each. Before that ride you can have breakfast inside the hostel (starting from 5:30am, ~35 RMB each, basic but alright).
The main desk was polite and they speak both clear Mandarin and English.
This time I was a bit disappointed by the WiFi, it worked in the lobby but not in our room. Also, the bathroom was a little bit too basic and badly flooded after taking a shower, no curtains or anything. Walls very thin, we woke up several times because of other guests.
Yet, for the price and the location (great restaurant just opposite) I would come back. Also Tunxi in general, apart from Huangshan is worth a visit. Better than four years ago, nice pedestrian street also on the other side of the river.
