I travel about once a year to Hanoi, staying anywhere from 2 weeks to a month and have always stayed at Hanoi Royal View. I volunteer for a nonprofit that works with poor families in the area and that staff have been VERY accommodating toward all of our various needs. They are very friendly, personable, and always respectful.
Great location right by Hoan Kiem Lake and tons of Restaurants. The hotel is clean and well managed. I can't say enough about how great the staff are. They are constantly cracking us up! And they are great with kids, we have tons of children and families coming in and out and they have been amazing.
Breakfast has something for everyone. They have eggs to order, and everything else on a buffet-type setup. For a westerner they have traditional breakfast of toast, fruit, eggs, meat of some kind, etc. They also prepare Vietnamese dishes as well like fried rice, spring rolls, meats, pho, bread, yogurt, etc.
It's not a fancy hotel, although it has upscaled from their latest remodel. It is a great price for what you are getting. My only complaint, shared with my travel partners, would be that the beds are a bit hard, though not unbearable. Also there is occasional street noise that filters in but we were on the second floor which may have been why.
However, the showers are always hot and have great pressure. If we've had any problem the front desk is prompt and sends someone up immediately for a clogged drain, etc. They have laptops in the rooms and free wifi which is great for people on business. We never had a problem with internet, and its a fast connection. We were able to skype, etc. without any problems.
