Selling house contents

Just wanted to take a moment to thank everyone for their input so far, it is greatly appreciated!!

I think the best way to describe the contents for sale is 'vintage' (not brown). Examples attached. if anyone is interested in anything I'm open to talking about

a quick and easy sale. 

But again, thanks for all the help!!

You could sell individual items or sets or advertise an estate sale on Facebook Marketplace. If you’re looking for someone to buy in bulk, a bit far for you but in the Algarve we have several businesses and charitable organizations that deal in purchase and resale of second hand furniture. There must be something similar up north. Also, I’m sure an auction house would also be interested. 

Sorry I don't know anything specific to Aveiro, but there are some places that do house clearances (but I din't think they will offer much). For example there is Associação Novo Sentido in Alfeizerão (Silver Coast).

There are active (mainly expat) Facebook groups for buying and selling all kinds of items in most areas - I've known people sell things very quickly on those. I have also seen garage sales advertised in these groups and even went to one once!
