We stayed here for 3 nights in August.

My husband and I loved the quiet ambience of this hotel after having spent hours at or nearby the Strip. The 2-bedroom-suite was great, as almost always with the Residence Inns. Nice, clean, comfortable. We had asked for a quiet room not facing the I 15, which was a good decision. No noise at all. The nearby airport was no problem to us. During daytime we could see the planes starting and passing the hotel nearby, it was quite interesting to watch them. And during nighttime there was no noice at all.

Our kids - teens - of course would have preferred a hotel at the Strip. But still they also liked the comfort and beautifuness of this hotel.

Especially the gardenarea with the pool is just brilliant. It is wonderful to stay there and have a relaxing time in and around the pool. It was very very hot during our stay (around 110 degree) so it was great to find the pool being really fresh and very very clean!!!

We did use the shuttle-service to and from the MGM-hotel, also to the Mandalay. From there we used taxis several times, f.ex. to get to the Hard Rock Cafe, which really is too far away from the Strip to walk. From the strip its around 15-25 USD by taxi back to the hotel.

During our vacation we noticed that the Residence Inns do not have Mon-Thursday-Managers Receptions any more. They've cut that service to Mon/Wed/Thursday-Receptions, at some places even less, just twice a week. OK. If one knows that, no problem. But if they offer a reception, they really should offer one. That really was the only bad thing we found at this Residence Inn. For the Monday we stayed there they had announced a reception but when we got there (and would have liked to have had a glass of wine or beer before using the shuttle to the MGM) we really were surprised to find almost nothing. Nothing to eat except for some fruit salat and just a few undefinable juices? No wine, no beer??? Hey, this was Las Vegas??? The management should better abstain from a reception like that. Because that wasn't one!

Apart from this the Residence Inn Las Vegas South was the best and most beautiful Residence Inn we have ever stayed at.

This hotel is south of Mandalay Bay, but not at all walkable to it as maps might suggest. Shuttle runs there every 30 min, which was fine for me, but not my mother. The shuttle takes you to the convention center. It's convenient in and out for the vehicle, but it's a 20 minute walk to the monorail. We did not take the MGM shuttle which runs once per hour. That may be a better bet.

The hotel is clean with large, comfortable rooms. We had a 2 br suite, as we had four people. Pool area is nice. Breakfast was adequate. I'd recommend the hotel to anyone wanting an affordable stay slightly away (but not too far) from all the noise of "the strip".

We were here for a trade show at Mandalay Bay for 5 days. I wanted a clean, reasonably priced hotel and we got it here. We had a two-bedroom suite and it was nice to have two bathrooms for 3 people. I love that all the Marriott properties are completely non-smoking.
There is something for everyone on the extensive breakfast buffet, which included eggs, waffles, fruit, cereal, oatmeal, bagels, donuts, fruit, yogurt and more. We used the hot tub to rejuvenate our weary feet each day after the show.
I saw other travelers noted highway or airport noise; we didn't hear any of that as our room was in the building farthest away from that overlooking the pool.
Everyone was incredibly nice and helpful. Special props to Brooke. I am extremely picky about my hotels and this place exceeded my expectations!

My wife, daughter, and I stayed there in April '08.
When we arrived at the hotel on Tuesday, the clerk immediately gave us a free upgrade. Sweet! It was a 2 BR, 2 full bathrooms,
kitchenette, living room, with 3 TV's.
We knew we were going to love this place.
Full breakfast each morning including hot oatmeal and raisins (the traveller's friend).
Each evening, except weekends, the manager had a social with free food such as spaghetti with garlic bread, or nacho chips with salad. So we didn't have to buy much food except if we wanted to eat out.
Later, they added a free lunch at the Courtyard by Marriott next door, but we didn't go there.
The hotel has a shuttle to and from Mandalay Bay every few hrs., so we didn't have to rent a car. Very busy traffic in town.
The hotel was spotless, staff were friendly, weather was beautiful, great pool.
Once you're at Mandalay Bay, the city bus, the Deuce, stops just across the street, then you can tour up and down the Strip by bus. Very handy.
Would we stay there again? Absolutely!
The bigger hotels don't offer as much as this Residence Inn with free breakfast, shuttle, etc.
