We just wrapped up a trip with 7 people to this condo at the McCormick/Millenium. We enjoyed our stay here. The pros to this place are that Hans is super responsive, responsible and accommodating. He's an attentive renter, which is always nice (though we never met him, just communicated by email and then text once we got there). Also the place has 4 bedrooms and lots of beds so it's nice when you have a big group. There are 3.5 bathrooms, and we stayed at a unit there last year that didn't have the extra bathroom so it's really nice to have when you have a lot of people. The bedrooms are decorated well, comfy beds, nice sheets/blankets, etc. The pool at the hotel is really nice and relaxing, and a nice getaway from the condo and heat. The kitchen is pretty well stocked, no major complaints there. There are also volleyball/tennis courts and other amenities (kayaking, etc) but we didn't use any of them. And also the place was clean and everything worked (sometimes with rentals this is not always the case).
The only cons are that the main living areas are set up a little strange...especially the "white room" with white walls, white couches and a white armoire. That room feels weird. I think it would be awesome to make that a tv nook, or game room or something. It's wasted space. There are also a few too many tables in the main living area which gives it a cramped feeling. Those are pretty minor, though, and overall I would recommend this place to large groups. I was debating between 4 and 5 stars, but in the end, I couldn't come up with anything significant enough to make it a 4.
