Airbnb is a common alternative to hotels, but here are some Airbnb selection tips:
Try to pick ones near the clinic area (Gangnam Station, Yeoksam Station, Non-hyeon Station, Sinsa Station). Picking places around here will generally put you in 8 to 15 commute from most clinics located in the Gangnam area (depends on traffic)
Try to pick places that have an elevator or are only 2 or 3 floors max stair walk if there is no elevator.
If you stay in a hotel or airbnb make sure you prepare it for your recovery.
Move things that you might trip on, cover up sharp corners, buy plastic covers if you think you may leak from your wound site, make sure you get plenty of pillows, so you can sleep on a 45 degree angle.
You could also try a homestay with a Korean family, and let them know if you are coming for surgery.
Note of Caution About Hosts
Be cautious when telling a host you are coming for surgery. Although we'd like to believe in the kindness of strangers, if they suddenly become invested in your surgery details and volunteering their time to assist you, then they may actually be brokering your surgery without your knowledge.
You should not disclose the names of the clinic you plan to visit until you have confirmed your final prices face to face, and have decided upon which clinic will do the surgery. If they ask clinic details before that time, then give them a random clinic name that you don't actually plan to visit. You can tell them the real clinic name after everything has been confirmed and decided upon, since it may be relevant for them to know for emergency contact purposes after your surgery.
Some red flags that a host may be acting as a covert broker is if they start volunteering services that are essentially done by medical tour agencies such as planing and arranging your clinic schedule, soliciting clinic recommendations, handling your personal information with clinics, escorting you to the clinic and interpreting for you. If you want all these things then you should just simply work with an actual medical tour agency from the get go, since they'll be upfront about these services and what their role and responsibilities are.
