We are on an outbound expatriation and needed a trustworthy tenant for our Stuttgart property in a very short time. With his experience and network Alex presented us the perfect candidate in a matter of days. Now Alex is our “Man on the Ground” in Stuttgart and helps us whenever local support is needed and we cannot be there in person, living and working thousands of kilometers away. That gives us a great peace of mind.

We enjoy working together with Alex and like his pragmatic and straight forward way. It is great to have this direct and personal contact with the COS decision maker rather than circling back and forth between some of the agents and headquarters of the “other guys”, where you are just another number in their database.

1. To find the apartment and negotiate with the landlord

When I appoint with COS as my agent for finding the appartment, COS made great effort to find the apartment which is relatively new and has a very good quality, And when the landload request many things such as submission of income certificate, company support letter, COS negotiated well with the landlord to have me sufficient time to complete requested documents. In addition COS did good negotiation to set up the schedule of the agreement with the landlord.

Thanks to COS, I could get current woderfull apartment on time. I really apprecaite their services.  

2. To settle parking card problem

When my parking card in my apartment did not work by misteke of the landlord, COS gave me the solution. Actually, I tried to contact the landlord, they ignored me and gave me no help. Then I contacted COS to advise me how to do. Although my contract with COD was over, but COS kindly took my case and negotiated with the landlord.

Immediately after COS negotiated with the landlord, the new parking card was delivered to me. I also apprecaite COS services.

We used COS Stuttgart to find our apartment and were thoroughly satisfied. Alex provided a highly personalized search that really took into account our family's needs and time constraints. He is responsive and meticulous in his approach to client services. We  recommend him highly, he knows the market well and we slept soundly knowing he represented us. -   03.03.2021 Nora
