Bringing personal belongings from Bulgaria (Istanbul)

I need to sell up my house in Bulgaria (near Veliko Turnovo) so need bring some of my belongings here to Istanbul. Unfortunately, my flat here (at Capa Sehremini) is on the sixth floor and no lift!

Does anyone know a reliable company to help with this? I guess a medium sized van would be enough as I shall leave all the big furniture and electricals in Bulgaria. Will be mostly boxed things, around six pieces of wooden furniture (such as desk, bookcase with glass doors).

Have run up against a complete blank at the Bulgarian website which used to be a big help.

Grateful for any leads.
Thanks.
