I asked for an early check in but never heard a response. In order to insure early access to the apartment, after 25+ hours of travel with my family I ended up booking an extra night prior to our arrival. Fliphaus then added another night to my additional night and charged me two additional nights.. so for a single night stay and a request for early check in, I ended up paying for 3 nights. They rejected my request for a partial refund even though I only stayed and checked in for one night. The host, via direct message was unable to alter my reservation or request prior to my arrival and I was told I would need to deal with Airbnb. Additionally the key to access this flat is several blocks away in a lock box and after arriving with many bags and two young kids - this was huge inconvenience as couldn’t simply get in… would not recommend any service by Fliphaus.. much better service and housing options out there in beautiful Buenos Aires.
