The apartment complex if fine for all the basics of apartment living. The apartment is big with good kitchen appliances. No laundry facilities in the apartment itself, so washing must be done in the laundry room. The higher level apartments have excellent views, particularly north-facing apartments in the North tower.
Management team are responsive and will address your queries. Maintenance team is particularly good.
The building is located right next to trains and express buses to downtown, which is a big plus. It is right next to parks and the lake which is great, particularly in summer.
Packages are delivered to the mailroom, which has problems with service - packages are often delayed or even lost. This can be stressful particularly when moving in.
The building is not particularly secure - there isn't much stopping someone off the street from reaching your apartment door.
There are better apartment complexes out there, so only choose Regents based on price.

Great for roommates

Many LLM students choose Regents Park. Not the best price, but the best option. Restricted access, rent included utilities, and near CTA bus stop and Metra train station.

I haven't had any major issue with Mac properties so far. I had some issues in my apartment with a leak in my basin and under the sink, but the maintenance was fast and diligent and they took care of it.
My main issue was with their accounting sector. Each month we had an issue with our bill and how they calculated things and it was so hard to find someone in their office that could help us.

The work done by the staff of Mac Properties is very sloppy. They send wrong rent invoice every month, they cannot be reached by phone with ease, and they almost never respond to emails. However the management team is always helpful when there is water leakage or malfunction of appliances.

View of the Lake, close to a 172 bus stop that goes straight to the law school, never had any issues with the apartment.

Regents is perfectly adequate. It is exactly what you expect from a massive high-rise complex: average amenities, available utility / door staff, annoyingly full elevators, and a generic apartment space. It was a great place to live for me during the first pandemic year because so many other 1 Ls were here, so it felt like being in an adult dorm where I could get to know people.

Good location in Hyde Park. Great for bussing to school rather quickly (15 mins) and for taking the bus up to the city (20-30mins). Walk to most restaurants and stores on 53rd. Fitness center is decent and always open. Laundry is OK. The market is convenient but pricey.

Cons: the building is old, walls are kinda thin, neighbors can be rather loud. The building also suffers from frequent (at least 1x/week) fire department visits, elevator issues, or criminal activity that can make it difficult to get to your apartment. Parking is way too expensive, and the garage is not very conveniently located within the building.

Regents Park has everything I need--gym, pool, business center, convenience store, package room to accept packages, front desk security staff. It's also very convenient to 53rd Street restaurants and shops, and to several grocery stores. The bus stop that takes you directly to UChicago Law School stops is directly across the street from the building, so the commute is as painless as it could possibly be. Have generally had positive and fairly quick experiences with getting help from resident services, maintenance, etc. I also like that a lot of other UChicago Law students and other UChicago grad students live in the building.

Regents Park is exactly average for a mid-quality high-rise in Chicago. On the one hand, its amenities (gym, pool, in-building good, cheap take-out food, and package receiving room) are nice. The views, particularly from south-facing (odd-numbered) units in the south tower, are quite good and the units get good sunlight. The apartments themselves are really nice quality, especially if you get a unit without carpet, and I've never had any issues with the utilities or appliances. Also, the location (along the 6 bus route and Metra line) is very convenient, especially for a Hyde Park apartment.

However, Mac Properties is a very difficult management company to work with. With the exception of quick and easy maintenance requests (like a clogged drain) they are slow to respond to most requests and often need frequent in-person reminders to take action. This is a bit easier because the building is large enough that they have a resident services team in the building, but it's still a hassle.

I'd say that the building is about 7/10 as far as high rises in Chicago (for the price range) go, but the management is about 4/10.
