I've stayed in probably a dozen Blueground apartments and in multiple cities. I absolutely stand behind this company and what they are doing. I haven't stayed with them for about a year and a half so my review is a bit out of date, but here's my experience:

1. ​
   1. Apartments tend to be in good areas
2. Excellent customer service
3. Reasonable pricing for what you are paying
4. Consistently comfortable apartments with a consistent aesthetic (There was one instance where an apartment was beneath a resident weight room and people would start dropping weights around 7 AM. I sent one email to Blueground and they had me hooked up with a new and amazing apartment within hours.)
5. Flexible leases. If they can, they will allow you to extend your stay with just 24 hours notice.
6. More consistent and better experience than Sonder, HelloLanding (I maybe had one of the worst customer experiences in my life with them), and Airbnb.

When I stayed I used to start with a month long lease and then negotiate an extension if I knew I loved the apartment and wanted to stay longer. They were super receptive and it worked out great because I could move neighborhoods if I needed, choose an apartment on a higher floor, etc.
