Dedication has a very clean and nice house. It have good bus connections to get there from the metro. She's also very friendly and informative though we didn't see her a lot during our stay.
As someone wrote before you should be aware of some house rules that are not stated on the website. For example you have to wipe down the shower after you have used it. You have to put your luggage on a small rug in front of the bed and keep it there.
The fan didn't work when we were there which made it a bit too warm for us during the day.
The kitchen was very nice, but could do with some more cooking tools like cutting knifes.
