It was great being able to park my car in a safe place!!! It is a great location with lots of local places to eat within walking distance. Make sure you hit Union Station - it's a very cool "market" type place that hosts many different food vendors from tacos to coffee, to ice cream, to adult beverages, etc.
We truly appreciated being able to use the washer and dryer In the apartment. If you're planning to sightsee it may be worth using the Metro. We probably should've planned to use the Metro from the start but you have to purchase some sort of $10 card each to use it. We ended up mostly using Lyft as we thought it may be cheaper/ easier, but towards the end we realized the Metro probably would've served us better. Another great note for adventuresome guests... the Lyft scooters are a must!! You get to see so much more of the city and sites without having to walk so much - and it's fairly cheap. We didn't spend too much time in the apartment, but it felt safe and clean.
