Great location but the hotel needs some attention
We selected the Holiday Inn Washington Capitol for the second time due to the location. It is the only hotel we could find that was close to most of the attractions. We checked in late on June 29th about an hour before the big storm hit the DC area. 
The two double beds room on the 7th floor that we were given was exactly what we reserved. After entering the room we noticed that where a fair bit of noise from the next room. I got the feeling that the person next door was entertaining a number of visitors at regular intervals and we were concerned that this would be happing all night long. We asked for another room and had to wait for about 20 minutes for a staff member to bring us the new keys. Not sure why we had to wait in the room since we offered to go back to the front desk. 
Our second room was on the 5th floor and was less noisy but for some reason we were again given a room that faces the subway tracks. The sound of the subway is very noticeable on the lower floors. We found the room acceptable but the shower/tub looks like it needed major repairs. We saw dated tiles and very bad grout work. 
The breakfast buffet was the standard Holiday Inn buffet. One change we noticed from the last time we stayed there was the waffles were now being mass produced. Waffles are made in the kitchen, stored in a tray and covered with wrap before being served. The waffles are then placed on the hot table where steam heats up the waffles. Waffles need to be crispy when eaten and not soggy and tasteless. I was told that management had made this decision because the waffle iron was needed to be cleaned often during a service. I wonder if that same management sampled the breakfast on a regular basis to ensure that their cost cutting decisions made sense. 
We also tried their dinner buffet. Word of warning – don’t do it. Subpar food with no taste. It was terrible. Go to the McDonald’s that is around the corner. In fact go the one of the chip trucks on the road.
