I stayed here twice in February. The rooms are really gorgeous and clean (admittedly I did stay in the most expensive private rooms as I wanted a break from sharing!) Don't know what the dorms are like but all of the guesthouse I've seen is beautiful and clean. The staff are very friendly and kind and really make the place. It's nice and quiet but only a 10 min walk from Khao San road. There were some younger travellers there and there is a communal area but it's not mega social like some hostels if that's what you're looking for. A little bit of luxury for me with hot shower, air con and Wi-fi!
