I would highly recommend Jason's place. It's the perfect location to zip into town quickly on the Metro or walk to the University in 15 mins. There are beautiful sights like the Oratory just walking distance, as well as many grocery stores and cafes.
The apartment is very clean and the room very big and comfortable. I enjoyed relaxing on the sofas in my room in the evening and cooking food in the kitchen. There is everything you need - extra blankets, wifi, storage. The bathroom has a brilliant hot shower!
Thanks Jason for your hospitality and being available to answer any questions or requests I had.
