The staff was nice and the room big and comfortable (we had the honeymoon suite). Some of the lights were not working and the wifi signal was poor, but in general the room was ok and good value. Breakfast was good although the room where we had it was not to big and we saw other guest waiting in the morning (so if you'd be in a hurry because you are leaving, try to be the first one there!). Anyway, the room was nice and we enjoyed our experience there.
Restaurant Tip: Go and try the bia hoy! (there are many street places around the Guest House)

The taxi pick-up from airport is smooth. We were welcomed by a refreshing drink upon arrival.
Discussed and finalized a Bai Tu Long Bay trip (since several recommended operators for Halong Bay trip were fully booked) at the travel desk. The staff (a young lady who's already a mother of two!) was very attentive and patience on every possible choice for the cruise.
The special deco in the room was a big surprise!
Breakfast was OK, a food and a drink per pax which is sufficient to me.
Location is superb, with the "best food at cheapest price" NewDay restaurant just few steps opposite it.
Though we didn't get additional night of stay (readers, please book earlier as this hotel is quite famous), the staff arranged another hotel which picked us up after the BTL Bay trip at no extra charge.
Generally, a decent hotel that will enrich your Hanoi experience!

To start things off, I think the guesthouse have a few locations? Anyway, the one we stayed at was on Ma May street. Location is the only best thing about this Guesthouse.

I was actually recommended by friends to stay at Hanoi Guesthouse. We reached late in the evening and only intended for a place to stay the night, hence, we booked a standard room. It was the smallest room ever, ever. To be fair, it was really cheap and the other room categories might be nicer and bigger - I have no idea. My friend who recommended raved about the staff of the hotel but I feel that they are a bit pushy for sales. Ala carte breakfast (only 1 choice) was also so-so.

The highlight of the stay was actually the Yin & Yang restaurant opposite the Guesthouse. They serve the BEST pho ever especially the wine stew beef pho.
