daily rates at hotels and airbnbs add up way too fast
monthly stays at airbnb's are much closer to the local rental price, usually 10-20% above a local lease, but without the issue of actually leasing
monthly stays are also furnished (whereas it can be very hard to find a furnished place to lease at all!)
monthly stays also get around most short term stay restrictions created specifically in reaction to AirBnB, which makes it much more comfortable for someone that booked to not have to worry about who we talk to in the building or nearby
I love being a situation to travel this way. Its pretty amazing to see that its currently become a crucial portion of their revenues.
