Aganazzar´s adequate abode

You conjure an extradimensional dwelling in range that lasts for the duration. You choose where its one entrance is located. The entrance is 2 meters wide and 3 meters tall. You and any creature you designate when you cast the spell can enter the extradimensional dwelling as long as the portal remains open. You can open or close the portal if you are within 30 feet of it. While closed, the portal is invisible.

beyond the portal, there is a plain abode with one room, a table, chairs for 8 people and a fully stocked kitchen, every time you cast the spell the house is cleaned  

inside the house there are two unseen servants that work as helpers, they can´t cook or do things by themselves
