Having not so many options for accommodation in Uppsala, Park Inn seems to be a very suitable one. Conveniently located 5mins on foot from the main train station (Uppsala C) offers a nice stay but a bit overpriced.
Rooms are pretty bright, with enough space. The ironing board is a great plus. Bathroom is small and only had a shower but was ok. Beds are quite comfortable and offer a good sleep
Major con: Guests have to pay for wireless internet access
Breakfast: Not so many options, limited tables, might find yourself waiting in a queue for an empty table on busy days.
