As I grow older I enjoy more getting gifts for the house, than little bits and bobs for me. I won't lie, it is a bit tricky to get something that is going to match the house's decor and please the house owner.
In order to avoid that, try to buy neutral pieces that can blend in with any decor. For example this stone lamp is a good choice for a modern minimal house, as well as a more classic house.
Mugs and cups are always a great and easy choice and most of the times you cannot go wrong with it.
