Citigroup has a sizable presence in the Detroit metro area, and if you're traveling there for client meetings, compliance reviews, or cross-office collaboration, your corporate rate at this Southfield Radisson cuts roughly 15% off the public price before you even factor in points. Code 40139 is tied to Citigroup's negotiated agreement with Radisson, so it works year-round without manager approval. That matters when you're booking last-minute trips to the Michigan offices and don't want to chase down a travel desk.
The Property
The Radisson Hotel Southfield-Detroit sits at 26555 Telegraph Road in Southfield, right in the middle of the suburban office corridor that runs along Telegraph and Northwestern Highway. It's about 28 minutes from Detroit Metropolitan Airport without traffic, though rush hour on I-96 or the Southfield Freeway can stretch that closer to 45 minutes. The surrounding area is corporate park territory, with plenty of chain restaurants, a Target, and strip malls within a short drive, but not much in the way of walkable nightlife.
Rooms at this Radisson fall into the solid mid-tier category, with standard kings and double queens running around 300 to 350 square feet. Each room has a work desk with an ergonomic chair and free Wi-Fi, which at Radisson properties is included for all Radisson Rewards members regardless of tier. If you need more space for spreading out documents or hosting a small working session, ask about the junior suites at check-in, as upgrades sometimes come through on lower-occupancy nights.
The hotel has an indoor pool and a fitness center, both open early enough to get a workout in before morning meetings. There's an on-site restaurant and bar that handles breakfast, lunch, and dinner, which saves time if you don't want to drive somewhere after a long day. Free self-parking is available, and the hotel offers meeting rooms if you need to host a working session without trekking to a client's office.
The Southfield Town Center office complex is less than 10 minutes away, and the area around Telegraph Road and 12 Mile has dozens of dining options from casual chains to a few solid local spots like Streetside Seafood. If you need to get into downtown Detroit, it's about a 25-minute drive south on the Lodge Freeway, and you can also reach Troy or Auburn Hills corporate offices in roughly 20 minutes heading north. For groceries or pharmacy runs, there's a Walgreens and a Kroger within a few minutes of the hotel.
Your Savings Breakdown
| Rate Tier | Rack Rate | Corporate Rate | Points Earned | Point Value | Net Cost | Savings |
|---|---|---|---|---|---|---|
| Standard | $130 | $111 | 2,220 pts | $8.88 | $102.12 | $27.88 |
| Superior | $210 | $179 | 3,580 pts | $14.32 | $164.68 | $45.32 |
| Premium | $340 | $289 | 5,780 pts | $23.12 | $265.88 | $74.12 |
Here's how the math shakes out on a typical night: the public rate runs around $210, and entering corporate code 40139 drops it to roughly $179. You earn 3,580 Radisson Rewards points on that stay, which are worth about $14.32 at 0.4 cents per point, bringing your effective net cost down to $164.68, a total savings of $45.32 compared to booking at the rack rate.

Stack Your Savings
If you've built up Radisson Rewards status through previous stays, your elite perks apply on top of the corporate rate. Premium members get a 10% points bonus, VIP members get 25%, and VIP status also comes with room upgrades when available and late checkout. Since Citigroup travel volume can add up fast, hitting the 30-night threshold for VIP status in a calendar year is realistic if Detroit is a regular destination.
The Citi Premier card earns 3x ThankYou points on hotel stays, which stacks well here since the corporate rate still codes as a hotel purchase. If you carry the Citi Prestige or have a co-branded card with broader travel multipliers, compare the earning rates. Radisson does not currently have a U.S. co-branded credit card, so your best bet is a general travel rewards card that gives bonus points on hotel spend.
Radisson runs periodic promotions, often quarterly, that offer bonus points for completing a set number of stays, sometimes doubling your earning rate on the second or third stay in a window. Check the Radisson Rewards promotions page and register before your trip, as these promos require opt-in. Booking midweek, especially Tuesday through Thursday, tends to yield the best availability for the corporate rate since weekend demand in Southfield is lower and the rate gap narrows.
Bottom Line: Depending on the season and room type, Citigroup employees using code 40139 at the Radisson Hotel Southfield-Detroit can expect to save between $27.88 and $74.12 per night once you account for the rate discount and the value of Radisson Rewards points earned. The hotel's 3.9 rating across nearly 1,500 reviews reflects a consistent, no-surprises stay that works well for business trips to the Southfield office corridor. It won't wow you, but it will save you real money and put points in your account every time.
