I've had an exceptional experience with OSI Offices. The professionalism and support provided by the entire team have been outstanding from day one. The work environment is always clean, well-managed, and provides an inviting atmosphere. A special thank you to Manager Mumbi Thande, whose leadership and attention to detail truly set the tone for the welcoming and efficient environment. Mumbi goes above and beyond to ensure tenants' needs are met and creates a sense of community that’s rare to find in shared office spaces. I highly recommend OSI Offices to any business looking for a reliable and supportive office solution.

Now this is the place you want to go to for all your professional needs. They have a limited controlled access, freedom to reserve rooms that will accommodate your needs for the day, and also detailed updates on package deliveries. OSI is walking distance from the White House, which is always a pleasure to see. Overall, this a wonderful place to call your office.

Law Offices of David Saffold LLC has been a long time (18+ years) and loyal customer of OSI. The virtual office model was great while we were building the business and clientele. Once we outgrew the virtual office model we decided to rent a full time office on the 1629 K Street NW 3rd floor suite. The offices are well-maintained and cleaned daily with a professional cleaning service. The staff at the front desk make our clients feel welcome and are excellent at receiving and distributing mail as well as receiving documents and payments from clients. Finally, the location (Farragut Square) and amenities (high-speed printer/copier/internet) cannot be beat! Very satisfied, David Saffold

Frequently Asked Questions

  • At 1627 K Street Northwest, Meeting Rooms can be booked by the hour. In addition, Private Offices and Dedicated Desks can also be booked on a monthly basis.

  • Most, if not all, amenities are available to you as a member, regardless of the type of membership. Some shared spaces, like the meeting rooms, need to be booked in advance and private offices are only available for those with a subscription. However, all the other areas, like the lounge, kitchen and breakout spaces, are usable by every member. All complimentary services are available and anything ancillary can be purchased or negotiated with OSI Office Space.

  • Storage in coworking spaces can be limited, with most of it reserved for members with dedicated desks and private offices. However, you can reach out to the coworking operator using the form on the right side of the page to see what options are currently available.  

  • Absolutely. Flexibility is one of the best parts of coworking. Most coworking memberships are month-to-month, so you can quickly adjust your space preferences according to your unique requirements and the size of your team. Whether that means upgrading the space or downsizing it or even completely changing the type of coworking subscription that you use, you always have the option to adjust as you go.

    It may be possible to adjust your membership before current membership ends, but you will have to discuss and negotiate directly with OSI Office Space, who is more than happy to help out.

  • The open desk is the way to go if you’re looking for a flexible workspace in an open environment where you can socialize with other members. Or, choose a dedicated desk if you want a designated space that also allows you to keep in touch with the community.

    A private office works wonders if you or your team need a quiet, secluded space to conduct your work and interact with people in your organization.

    It’s important to understand the different types of coworking arrangements available to you, depending on the type of work that you do and its duration, and whether you’re a solo worker or part of a team.
