Other very important issue about the 5 stars is the pricing, people undestand 5 stars as a 5 star hotel, the prices of a 5 star hotel is 5 times the price we have, so if AIRBNB pushes us to lower the prices why dont change the 5 star system?, we cant give 5 star service when we charge 20% compared to a 5 star hotel rate, the beds, furniture fixing bathrooms cost the same for them than for us, with the difference a 5 star hotel are companies that earn millons of USD, we DONT!!!!! so stop making the prices lower , because the only thing is going to happend is make the hosts rent it for long term people, not turists and without hosts no AIRBNB , i know AIRBNB is so big that provably doesnt care about loose some hosts, but in some point AIRBNB is going to get competition that now doesnt exists, you are sucesfull because you have a diferent way and porcentage to charge people, but whatch out can be copied easily, so please take more care abut the hosts!!!
