We live just a few miles from this place... and had to make a last minute reservation due to a construction emergency at our home. The owner was very responsive and got us into the unit within just hours of my first contact. They remained kind and responsive when we had to extend our stay by a night. That was the biggest plus to us.
The unit is very nicely furnished and spotlessly clean. You'll also have everything you need. Towels are plentiful in both bathrooms, and shampoo, body wash, and soap are available. The kitchen is very well equipped, from the big considerations like full size appliances, dishwasher, microwave, etc. to the smaller touches like dishes, soap, salt and pepper, etc. There is a full size washer and dryer in the unit with soap and fabric sheets provided. We were able to move RIGHT in with just our carry ons and some food. AC works well.
The pool and hot tub are quite small (and a very short walk across the street to the sister building), but our daughter enjoyed them... and the pool deck itself is very spacious and nice. As locals, we knew what to expect from downtown Glendale... but be aware the unit is a short walk from the Americana, not directly overlooking it. The city is walkable and you'll find plenty of restaurants within very easy walking distance as well as the two large malls (one indoor, one outdoor).
