90 University

The residences are available to the general public on a nightly, weekly, or monthly basis during the summer.
This review is for Marchand residence. It’s a traditional, dorm-​style residence. The rooms have a bed, a desk, a closet and drawers, and not much else. The prices are very low, and your expectations should be realistic. The bathrooms are shared, the kitchens are shared, and there is no air conditioning. The bedding is on the threadbare side, and the amenities are minimal (a towel, a washcloth, and some soaps are refreshed each day. There is daily maid service.
There are useful reviews on tripadvisor, and the best pieces of advice I read there definitely bear repeating here:
1. Bring a fan. It gets hot in Ottawa in the summer, but it’s bearable if you have a fan. If you don’t, prepare to swelter. To quote Matthew Broderick, «It’s hot. It’s Africa hot.»
2. Bring an ethernet (network) cable. There is free wired internet in the rooms. I brought a cable. It turned out that there was a cable in one of the drawers in the room, but I wouldn’t count on it. The other thing is, the cable in the room is very short.
3. The price and location make up for the shortcomings (in my opinion). Great restaurants and things to do abound within walking distance.
Did I mention to bring a fan? Seriously, bring a fan.

Having booked online, I saw that the room was a decent size for all intense purposes, its just a bed with a TV, small table and two seat couch, it also has a small bar fridge. The bathroom is a good size as well with a shower sink and toilet, not that I’d take a bath in a hotel, but its not an option here. Also free WiFi is available.
I stayed on the 20^th floor and I don’t know if they shut the heat off already for the year, but there were a few cool nights and I had to put on my sweater even though the thermostat in my room was fully cranked to heat, the temperature kept falling.
The bed is hard as a rock, I assume its some kind if dense foam and it was the worse for comfort, but I’m sure they don’t have to replace them as frequently as they would a regular spring mattress.
I liked the look of the room, and was surprised to see a flat screen mounted to the wall, but at the end of the day (literally) I’m looking to be comfortable and sleeping here gave me a site back daily.
The price is decent for the area at $ 99 per night, but I’d be willing to pay a little more next time for a comfortable sleep.

Bring alcohol

90 University is a dormitory residence for first-​year students at the University of Ottawa, but the 20^th floor has studio-​style guest rooms and apartments for the long-​term and short-​term stays of other individuals, all year round.
90U is by far one of the best residences on campus. The front desk reception in the lobby is open 24-​hours a day. There are laundry facilities on-​site, as well as Le Rez Café on the ground floor, which sells sandwiches, snacks, and coffee, and study and student lounges on each floor. Each suite has two bedrooms, a bathroom, a kitchenette with a fridge, microwave, kitchen table, and chairs, as well as maid service. Each bedroom has a double bed, desk, chair, dresser, separately controlled air-​conditioning, Internet, and even a TV with cable included! Some units are also designed especially for wheelchair accessibility.
The maid service is for the common areas, and the kitchen and bathroom in each suite, but it’s not as great as it sounds. A friend of mine lived in 90U and it was pretty obvious that a dirty cloth was used to wipe everything, since there were foreign hairs on different surfaces, none of which belonged to my friend or his roommate. It’s probably best to do your own cleaning.
The beds are the largest I’ve ever seen in any dorm room at either Ottawa U or Carleton. The only problem is that they take up most of the space in the room, and some people have trouble getting to their closets and opening their bedroom doors all the way.
