Rooms were clean and service and staff were responsive and very nice. The designs of the room is on the older side (as others have mentioned), but we were pleasantly surprised (and pleased) with the size of the triple deluxe room that had a large window. The location is ideal if you want to be in the heart of District 1 and the walking street - it is an extremely lively and busy area with lots of car & motorbike and foot traffic, so it can be chaotic right outside and quite noisy - luckily we were on the 8th floor so street noise wasn’t as much of an issue and it was nice to have a view of the park outside.
Cons: The hotel was a bit hot temperature wise, and we wished the AC in our room was stronger, given hot temps in HCMC. The shower had poor water pressure, and the layout of the shower head and bath tub was a bit awkward. Not all the plugs worked and we wished that more plugs were in more accessible places in the room as we had 3 people needing to charge devices/use outlets.
It wasn't anything too luxurious or over the top concierge service. Given the affordable price/value, Elios is a good value for what you pay, and an overall solid place to stay!
