A car cannot get down the ally where the hotel is. It is a 30 second walk. However if the hotel knows you are coming a staff member comes down and meets you thus also helping you with luggage. I would use their arrangements and it is not that much more.
We stayed in the Hanoi Elite from 10th-14th and found it very quiet. Our room was at the back of the hotel, so maybe the rooms facing onto the street are not so quiet. There are two rooms on each floor probably prudent to ask for a room at the back. Hope this helps, it's a lovely little hotel, staff are really nice.
Greeting from Hanoi Elite hotel. Thanks for your question and concern. The rooms on second, third and even the forth floor are quite quiet that can meet your expectation. Please do feel free to email us if you need any further information and travel helps. Your sincerely, Hanoi Elite hotel management.
