Thank you!  Can you list the facility codes for each of those apartment IDs (3 4 6 11 12 13 15)?
select T2.facility_code from Apartments as T1 JOIN Apartment_Facilities as T2 ON T1.apt_id  =  T2.apt_id WHERE T1.bedroom_count > 4
listing facility codes for specific apartment IDs involves selecting 'facility_code' from a join between Apartments and Apartment_Facilities tables; the condition on bedroom_count > 4 is unrelated to listing by specific apartment IDs.
