select a.hotel_id,a.hotel_name ,a.location, b.rate hotel_info  left join rooms b on b.hotel_id=a.hotel_id  group hotel_id

how minimum room rate per hotel?

you can use mysql function min() such as

select a.hotel_id, min(b.rate)  hotel_info  left join rooms b on b.hotel_id = a.hotel_id  group a.hotel_id;
