AVOID! unless you want endless incompetence and bureaucratic shortfalls. There are several system failings here. First - good luck finding the address! When you do call in - you get someone sitting thousands of miles away who also has no clue and there is surprisingly little in the way of local representative to contact you our assist you! Shocking. NO ONE in your local location to contact even during regular office hours. Next, Even when I tried to extend by 1 day after staying 3 weeks there I was told there was a glitch with the system and the extension did not go through. So I had to move - fortunately just one floor up! But not too soon, they required ID. This is after they already had my ID for my previous stay for 3 weeks. This additional one day required new ID with selfie photo and it had to go trough their app. For some reason it did not go through to them even after they took payment. So I was unapproved and I am still awaiting my refund for the additional one night. Are you getting the picture of why this is a seriously faulty system? In short, its overly bureaucratic, incompetent and not at all user friendly. There are no local staff, no human touch. Its really quite a shame given the property location and condition is quite nice! Competitors like One fine Stay, plum guide and indeed regular AirBNB hosts have a far better handle on such matters than SOnder! Its beyond teething issues. They claim ID process was necessary for security issues. But I was able to go back into the building to pick up my luggage. Doubt they changed building or apartment code then? Rubbish security concern.
