The rate for accommodation
If you are looking for a hotel with a low price, I recommend this hotel, "Sleep Inn". This is cheap, comfort is mid level, and some affordable facilities there are.
First of all, speaking of the location and the area around it is great. It is located on Rockville, Washington D.C. and only 20miles from the White House, the Washington monument, the university of Maryland and Smithsonian institution. Also I arrived at the Ronald Reagan Washington National Airport and it took for me to get to the hotel less than two hours by car from the airport. In my free time, I went to the Montgomery mall. This shopping mall was huge and had about 190 stores. I really enjoyed shopping there and I ate sushi-roll at the food court. There were various kinds of restaurants so you could eat whatever you liked. Therefore, around this hotel, there are lots of kinds of great facilities.
Second, about the actual hotel, this is not super comfortable. Actually, I stayed here for about three weeks when I was on my school trip. I think whether this hotel is good or not depends on your purpose. I cannot recommend it to people who are really sensitive. That's why you can stay there only $70 for a day I think. Speaking of comfort, there are many kinds of good materials. I was glad that there were laundry machines, free-wifi, PC, hair dryer and I held a party in the big multi-purpose room. Also, I had buffet style breakfast for every morning. The price contained it too. They were pancakes, waffles, toasts, or any other American foods. It had kid's plates too, so I think family can also enjoy it. During summer, you can enjoy swimming pool outside but actually I visited there in spring so I couldn't. Additionally, staffs are friendly. Not always but often they bring me my baggages. I think they are relatively casual, not so formal but they do things which they should do at least. The most problem was, when I had a breakfast, plates were really dirty. I meant, they were not washed and cleaned up completely. It was really disgusting.
Anyway, if your purpose is just to stay, you will be satisfied with this hotel. Just enjoy the sight seeing around there!!
