SALE NOTES

Office for Sale Set Up as Coworking Space on Prestigious Calle Castelló, Madrid  
Office located in an exclusive high-end building in the heart of Calle Castelló, a street parallel to Príncipe de Vergara and perpendicular to Goya, within the prestigious Salamanca neighborhood. This is a prime area, very well connected, with metro and bus stops just minutes from the building.  

There are two sales options available. First, the sale with profitability, as the property is currently leased to coworking operators.  

It generates a monthly income of €7,000, with a mandatory three-year lease agreement, resulting in annual revenues of €84,000 and a 5% return. This option is ideal for investors seeking security and stability.  
The property guarantees rent + expenses for the 5 years of mandatory compliance by the tenant.  

The second option is the sale of the asset free for personal use—such as a corporate headquarters, professional office, or clinic—or for direct operation as a flexible space or coworking. In this case, the potential annual income is estimated between €140,000 and €180,000, depending on occupancy levels. This alternative is aimed at operators or managers looking to maximize profitability.  

The property has a total area of 270 m², fully equipped and operational. It includes three spacious parking spaces within the building, with a total capacity for 32 to 34 workstations. The layout consists of eight private offices, common areas designed to optimize comfort and productivity, meeting rooms for 5 to 14 people, a phone booth, kitchen and office space, as well as a shared area with a sofa and armchairs. It features three bathrooms (men’s, women’s, and accessible) and a shower, as well as a rack room and technical area.  

Regarding equipment, the space includes state-of-the-art Daikin climate control with individual settings for each office, motion detectors in common areas, independent radiators, telecommunications network, high energy efficiency, modern furniture, concierge service, and parking spaces within the building.  

Its main advantages include its prime location in the Salamanca neighborhood, the possibility of investment in two modalities—with immediate profitability or high income potential—its turnkey condition with premium services, and the inclusion of parking spaces, a highly valued feature in this area of Madrid. Additionally, the building maintains an exceptional level of quality and prestige, characteristic of a high-end office property.
