We have just returned from a 14 day trip ti vietnam and stayed at the long hotel in Tam coc for three nights in april 2010.
We stayed in a twin room for the first night as we were delayed by one day arriving into the hotel due our own trips plan changing - the twin room was clean and very comfortable - clean sheets, floors, bathrooms really helped as we actually expected this to be our cheapest and therefore poorest quality hotel of our entire trip, but it was great - i expected the worse but was surprised - the rooms have plenty of room and do the job - our room was on the 5th floor. The only thing to be careful on this floor if you have kids would be the open sided terrace - and lack of outside lights at night time on this floor only.
we then moved to a double at the front of the hotel (room 500) with the most amazing view of tam coc river and hills - beautiful.
the room again was clean and had plenty of space - the only thing is the curtains slightly smelt damp/ musty, but it goes without saying for a hotel in this area. - it was not a problem and would highly recommend this hotel instead of any in nihm bihn - if you need a hair dryer, you simply ask reception and they give you one that is really good - its not a problem.
Tam coc is quiet and has amazing views and allows you to access some amazing little temples easily from the hotel and be there early in the am before any coach parties turn up around 11am - if you stay in nihm bihn you are on dusty, noisy main roads and have to taxi out to get to see the country side.... tam coc is already where you want to be to see everything beautiful in this area.
the only downside to the hotel as other reviews, is that the breakfast really does consist of some french bread and sweet breads with no real jams or anything to put on them. they will cook you some eggs, but in half a bottle of oil, so clearly instruct them on what you want and then its not so bad! - coffee and fruit juice are available and also some local noodles and spring rolls etc, but they turn off the heaters when no one is there, then they turn them back on when the next guests arrive, so i did not eat much other than toast for breakfast as worried about food poisoning!
dinner is better as they do have a menu full of local dishes.... most seem to taste the same or very similar despite what you order, but a few nights is no problem, but on our third night we were defiantly a little bored!
defiantly recommend this hotel for great location - make sure you hire bikes and turn left out of the hotel and cycle down to the temples and also there is a cave that you can boat thru which as great - defiantly also the boat ride from outside the hotel is beautiful and very peaceful..... ignore the lonely planet saying that you will get hassled by the boat women - they do try and sell fresh pineapple and the occasional emb, but have a laugh with them and they are great back - its is really not a stressful experience in anyway = great time in Tam Coc and would go back.
each room also has its own computer and tv, which is great if you want to catch up with home or check out further info for your forward trip.
