Ive stayed here a couple of times for overnight stays near the airport. The most recent on jan 20, 2012. It's a nice hotel with good amenities, the lax shuttle comes very frequently, rooms are a good size and generally are clean. Check in however can be a little slow depending on the time of day or as in my last visit due to someone in training. Overall I wouldn't hesitate to stay here again if I needed to be close to the airport or for business. The prices are really great, often under $100 per night.

We stayed at the Renaissance twice, at arrival and departure.

Room and service was what should be expected from a 4* hotel, however it is a bit dated. We remember that the food in the restaurant was very good. We would stay here again, but not for more than a couple of days.

Spent a night here when I was stranded at LAX overnight. Renaissance hotels can be all over the place in terms of design and quality but this one is very good overall.

Hotel lobby is nice if a little dated, and the rooms were very nice. Phenomenally comfortable beds, and as most other reviewers have noted, the rooms are very well insulated from airport noise (and from other rooms). I slept great. The hallways are a bit tired and cheap looking - so the nice room was a pleasant surprise.

Too tired to eat elsewhere, I had dinner in the bar. The meal was fine, but horrendously overpriced for what it was. Bartender showed little interest in me or the other 2 bar patrons. Breakfast in the restaurant was excellent (great selection, good quality) but very overpriced. $17 for a cold breakfast buffet? $23 for hot buffet? REALLY? I expect pricier food at a Renaissance but I thought this place was over the top for the quality.

The concierge I worked with to coordinate getting to Orange County was excellent. She was friendly, knowledgeable, and very efficient. I was most delighted with check-in and check-out. I'm a Marriott Rewards member, and used to quick service, but my check-in was completed in less than 30 seconds (but still very friendly).

I'd stay here again for the rooms alone, and the (mostly) excellent service was a great bonus. If the food was a better value I would have been delighted.

We had stayed at the Hotel 4 years ago and it was the logical choice for us to spend the night near the airport. The position is first class - our sons love being able to see planes on their approaches. Also the airport shuttles that run every 15-20 mins are excellent.
What we did notice this time was that the rooms seemed a little tired with wear and tear. We had two adjoining rooms that were adequate and I guess for just over $100 a night you get what you pay for.
The prices in the breakfast and bar areas are expensive.
Front desk staff were efficient without being over friendly.
