@Rishabh24 Honestly, I would remove the word cozy from the description. It's definitely not cozy. You'd need to up the decor, add some color and some warmth for it to be even close to cozy. Area rugs and some throw pillows would go a long way. If you don't want to invest in additional decor, then describe it for what it is. It looks like a very utilitarian place to stay.
And don't let guests receive mail at your address regardless of how long they stay. You have to be wary of tenancy being established if you're going to do long stays, depending on the regulations in your jurisdiction.
