We enjoyed staying at Matthew's. It was in a great location that was within walking distance to some great restaurants and shops, and it was just outside of the city.
We had some trouble with parking on our first night since the area is zoned, but once we ended up being out exploring so much that the strict parking times didn't really affect us.
The apartment has what you need for a comfortable stay- comfortable bed, mini fridge, clean bathroom.
We had some issues with not being able to access the rooftop, but from what Matthew said, he'll be checking in with management about it.
The shower has a little lever at the top (hard to see if you're short) that controls water pressure. We thought that there wasn't pressure for the first few days of our trip, but then we realized how to control things!
There is no iron, but there is a steamer. It's relatively effective in getting wrinkles out after traveling. Matthew told us if we wanted an iron, he'd find us one. We made due without it :)
The neighborhood was quiet and safe. We really loved it and will definitely be back to the area. Capitol Hill is wonderful!
