The hotel is in a great location. I had been staying in hostels in Australia, staring with up to 5 other people before this hotel so it seemed like a good deal to have my own room and own bathroom. The staff have just enough english to get by but you might get a bit frustrated if you expect too much from them. There is a nice roof top pool were you can sunbath and a basic breakfast is included

Stayed here many times over the years traveling to Thailand, great location, make sure you get room with Wndow and if possible not over looking the street, Great roof top pool

It is Ok to stay there for maximum 2 days. No friendly staffs at the reception. Even though it is a backpacker lodge, it is expensive. Toilet rolls are very cheap in quality. They have a swimming pool and a massage parlor on the top floor. That is the only enjoyable thing which i found there other than chicks from different countries competing to expose body parts and waxes legs!!

We stayed here twice, 1 night each time.
Room - the first night we stayed they only had a few double rooms left and it ended up being the rooms overlooking Khaosan Road. The staff did warn us that they weren't the quietest rooms but we took them anyway and paid the price. Luckily we were used to the noise from staying at Khaosan Palace for 3 nights previously so had a reasonable sleep. If I never hear Rhianna's "we found love in a hopeless place" again I will be so happy and it (and other radio hits) gets played on the hour by most of the bars all night long.
The next time we stayed we were smart enough to ask for a quiet luxury room which was much better but major drawback - the room vaguely smelled of urine. As we were exhausted from travelling all day and we knew the hotel was full, we basically just put up with it. Our friends had the same sort of room as ours and they were perfectly fine and really happy with it. So I think we just got unlucky. It would make me hesitate to stay here again though as there are many places to choose from.
Location - D&D is right on Khaosan Road so it really depends what your after from your trip. K Rd is an experience. It's also close to the Grand Palace and the river and some of the wats.
Value - excellent value for what it is. There are much cheaper places about but the rooms do reflect that and D&D's rooftop pool set up can't be beat.
Breakfast - This does get busy so go early if you can drag yourself out of bed.
Service - we actually had quite good service here. The staff were helpful and friendly. They also let us store our baggage for a few hours on a day that we weren't even staying there - for free. And it was all still there when we came back - bonus.
