Well, the whole process didn't worked as it was supposed to be. I asked some guidance regarding the check-in but could only get an answer almost 48 hours later. I even tried to call in the morning prior to my arrival in afternoon, but got no response.
Without any guidance, I went to the property at the agreed hour. The check-in arrival guide, didn't helped that much because I couldn't find the lockbox. To this extent, I was helped by others guests in order to get inside.
When I entered the room I was supposed to stay, it was a complete mess. There were garbage, dirty linens and broken appliances. The room was also different from the photos. I immediately searched for another place and later got a full refund.
Moreover, I found that the hosts doesn't live in the property and they basically rent it all over. There are 2 floors with 6 rooms in total, if I am not wrong. Some for longer-term stays, other for shorter periods. It is basically some kind of co-op/shared housing. I also found that they are not there everyday, only from time to time. I wouldn't see any problem in this situation if it was clearly communicated from the beginning. I feel compeled to report this in order to allow other guests make their best decisions. For some people it might work, for others not.
In any case, as other reviewers have said, the neighborhood is a bit sketchy and I was told by other people familiar with the region to avoid walk in the streets by night.
A potential good aspect is that it is close to a supermarket and to Cottage Groove Green Line station.
In any case, I hope Silvia and Joshua could improve their communication processes making it clearer and faster. Also I really think that the listing could be MUCH clearer in terms of the real functioning of the house and the interecation dynamics with the hosts. I must confess I couldn't see by any parameter how they are ranked as Superhost. It wasn't near any of my previous experience with hosts with such rank.
Lastly, I hope this review help other guests to make their best decisions by providing information I wish I knew when I booked the property
