3 stars is a bit high. The hotel room is small, the glass windows are covered with mud, the bed is small, the quilt is damp, and there are no toothbrushes, slippers and toiletries. There are few types of breakfast. The price of the buffet in the evening is the same as that of the Sheraton next door. The dishes are much different. Drinks at the buffet are charged separately. The only relief is that I chose a sea view room and relied on the sea to survive the past few days.
Totally fine for an airport layover. Not as nice as the photo looks much more basic. Wifi didn’t work for me. Note no wifi at airport, and you need to call them on WhatsApp to arrange pick up. Return to airport at 5am was easy to arrange. 
we were two friends having two rooms and were staying during Ramadan, so we were the only guests there I guess.. they took care of us so well, we were very satisfied and will stay again in the near future
Un séjour absolument exceptionnel au Lounis !
Dès mon arrivée, j’ai été accueilli avec un sourire sincère et une attention remarquable.
L’ensemble du personnel mérite une mention spéciale pour sa gentillesse, sa sympathie et sa disponibilité à toute heure, on sent réellement qu’ils aiment leur métier et qu’ils veulent que chaque client se sente comme chez lui.
Les chambres sont impeccables, confortables et très bien entretenues. Le rooftop du restaurant, où l’on peut aussi prendre le petit-déjeuner avec une vue imprenable sur Santa Cruz, est tout simplement magnifique, un vrai moment de détente et de plaisir.
Je recommande cet établissement les yeux fermés à tous ceux qui souhaitent vivre une expérience hôtelière chaleureuse et haut de gamme à Oran.
Un grand bravo à toute l’équipe du Lounis Hotel by Atlantis pour leur professionnalisme et leur sens de l’accueil !
The staff very nice and helpful,
The lobby design of hotel is full of style of European,very beautiful.
The bed is good and I sleep ver well
Thanks for the staff of hotel
I've tested all 5 star hotels of Oran and I give a 4 star at 2 h
The atmosphere in this hotel is a little limited
Breakfast is correct but not worthy of a 5-star breakfast
I've not tested the other comforts to name Jamal sauna ...
Good price quality ratio
