I contacted Konstantin after realizing that I had ordered incorrect sizes  in an IKEA order that had already been delivered by IKEA.  Konstantin and his team purchased the correct furniture from IKEA, delivered the furniture, picked up and returned the incorrect items, and assembled all of the furniture.  This was all accomplished in one day after I had contacted him in the late morning !!  Konstantin and his team were courteous, efficient and the pricing was very fair.
I would highly recommend this company for all of your IKEA needs. I do not normally post online reviews for companies but considering the excellent customer service that we received, I felt they well deserved an excellent review.  Job well done! Thank you to Konstantin and your team.
