Unacceptable actions- we almost slept on the ground, tired after whole day of walking in Milano in 35 degrees.. 4 girls. Middle of the night. Hotels around full. Because of "low battery" in a building door lock. outrageous behaviour !!!!! WE COULDNT GET INTO THE BUILDING using stupid code and online lock. It showed "lock is offline - please contact your host". Host was of course not available, actually we dont know if he/she exists, we contacted the company which run this rental and with the airbnb - both of them tried to help but at the end - said there is nothing they can do. The lock can be fixed in the morning the next day !!!!!! And that we can go to another hotel, but unfortunatelly there was nothing available around , especially in aprox. same price that they allowed us to look for. We were not surprised - ofcourse there is everything FULL in the middle of the summer, in Milan, at midnight !!!! And at the end neither host's company (ALTIDO) no airbnb company could help, they left us with no place to sleep in the night (it was all from 00:00 to 2 AM). We were calling in the middle of the night to sleeping neigbours and one of them went down to open.. horrible !!!!! How you can only count on a stupid lock with no other secure. In addition shower was broken and air conditionair didnt worked.. but in our situation it was just a detail.. but still. I dont reccomend this host, altido company and AirBnb company in general for not caring about our safety.
