1. The check-in process needs to be organized prior to the guests arrival, not 2 hours before on the same day. Our group was visiting from another country, so to be asked for additional documents (specific passport info) and payment (city tax fee) while we were boarding our flight a couple of hours before our arrival was completely unprofessional. This Airbnb was booked on August 22nd and our reservation was on September 19th. That was more than enough time for the host to contact me to request this additional information and collect the fees.
2. We were told there was a "welcome" team member waiting for us, but when we arrived no one was there.
3. We were told the key to our unit was in a lock box located in the lobby area. The code that we were given was incorrect, and we waited for over an hour until the host finally sent someone to let us into the unit.
4. Once Alvaro arrived, he brought a bottle of wine and chocolates which was probably the only pleasant experience we had.
5. There was a strange lingering smell directly outside the building and also inside the unit near the first bedroom.
6. The washer/dryer was a bit difficult to use. Instructions would have been helpful.

I was very disappointed with this entire experience. Our first night was spoiled due to the host's lack of communication. We missed our dinner reservation, and also missed out on the sightseeing we had planned that first day. We were only refunded a partial amount of the first night (not even 50%).
I truly hope that no other guests have to go through this same experience in the future. Better communication and organization on the host's end would have prevented this entire fiasco.
