Good hotel, on the wrong side of the tracks
The Omni experience is usually pretty good, and this hotel lives up to the standard of the chain. The hotel is modern, stylish and has a solid feeling of quality all around. The rooms are standard size, well appointed and have great bathrooms with fabulous showers (no tubs in our standard room type). We were staying with our child, so we opted for the two beds/room option. Unfortunately, the Omni uses doubles rather than queens, so the sleeping arrangements were tight for my wife and I. The comment in the title of this review refers to the horrific location of the Omni immediately next to the railroad tracks. Each train (and there are MANY on a daily basis) sounds its horn repeately as it approaches each intersection (and there are MANY intersections), so be prepared to hear a series of loud horn blasts roughly every 30 minutes in the evening and night hours - apparently sounding the horn is not obligatory during the daytime. The hotel actually provides two free pairs of earplugs in the nightstand drawer, anticipating that you will need them! The concierge said the city is working on making the Gaslamp District a quiet zone for rail traffic, but who knows when that will be enacted (if ever). To be fair, not only the Omni suffers from this noise issue - about 80% of the hotels in the area of the convention center are adjacent to the tracks. So be prepared for a bad nights sleep unless you can ignore a freight train passing within 20 yards of the hotel!
The restaurant of the hotel was quite good for both breakfast and dinner, and in our opinions reasonably priced for the quality. The staff was attentive, courteous and helpful. Overall the Omni experience met our expectations, with the only detraction being the proximity to the tracks. I dont think a better option exists in the area, so enjoy the hotel, and utilize your complimentary earplugs!
