The sentence is fine, and I understand it to mean there's a feeling of friendliness in the house. In Australian English, we use "it's the vibe" as a catchphrase (крылатые выражения) to mean, "I don't really understand any of this but I'm sure it proves my idea is right".

I would say it a little different: Our house has a warm vibe*
