I spent two nights here while visiting my daughter who is in college here in Denver. Gabriel and Vanessa's place was well located relative to her campus - what I didn't fully appreciate until I stayed here was how great the location is relative to... everything. Outstanding access to downtown, parks, great restaurants. All of it.
The unit is spacious and would be very comfortable for a longer stay (including a small but nicely equipped kitchen). My only concern was that being on a lower level the space might feel like a basement. The reality is that is has windows on both sides and as a result it is very pleasant. It is not a tall space (I am 6' tall and in a couple of spots I just clear the structure). If you were much taller it might be a consideration.
The furnishings were all very nice... clean and contemporary (think Ikea). Bedding and mattress were awesome. Lots of hangers and places to store things which was also very thoughtful.
As noted in the listing - they live upstairs. And there were times when I was aware of them being here - but it was a complete non-issue and I rather liked the sounds of family nearby.
To me there are two types of AirBnB units. Ones where you feel like someone has moved out so you can stay. And then ones where you feel like it is your apartment. This is definitely in the second category (which to me is key).
Gabriel and Vanessa were very easy to communicate with and super accommodating - I would be eager to stay here again based on how great they were, how nice the unit was and the outstanding location.
