Great location, near most major downtown history Hanoi sites to visit; yet located on relatively quieter streets, in walking-distance near necessary amenities (right next door to mobile phone store, steps from many restaurants).
The major asset of our stay at My Moon Hotel Hanoi was our superlatively great experience with hotel staff. All of them: from internet concierge, reception desk (all shifts), tour & tickets, bellboys, breakfast on-order kitchen staff were attentive to our needs, extremely helpful and creative to assist us in this stay, for our first visit to Vietnam; staff even took time to escort, show how to safely cross streets in VN.
Lobby: clean, comfortable; welcoming both for check-in & check-out, even welcomed us after we had already checked out & returned to pick up luggage before departure to our next city. The lobby has a full bathroom; they offered to/let me shower after hot, sweaty tour, on night of check-out - Wonderful !
Elevator: works fine, beautifully decorated.
Room: spacious for # of beds (1 queen + 1 single - noticeably more space than in equivalent hotels/rooms in Saigon/HCM city), spotlessly clean. Was furnished & stocked with amenities: small refrigerator, electric hot-water carafe, key-lockable "safe box" in the clothes armoire. Beware food/snack amenities: take care, recognize that complimentary water bottles (clearly marked, can also get spares from front desk) are not same as minibar items (charged, including water bottles in refrigerator).
