I agree with the ambassadors. Living in the city is really nice, but the private halls do not really put on anything as such. My daughter was in landlord accommodation for second year, but then in third year she stayed at Penny street (Hello student) and she loved it. They only put on a meet and greet at the beginning and not many turned up lol. But she did love her house mates. They were mixed sex, mixed years from first year right up to phd level. So if you do decide to do private halls in the city, these are the ones I know of:
Aparto in Bulk which is north of the city.
St Leonards House
Cityblock - Penny street, Marston House, The Gillows.
Hello Student - Penny Street x 2 properties, Victoria Court
Advantages of private halls is that should you just team up with 1 or 2 other people and dont fancy a house, then you can group together and join with other groups/singles and meet even more new people. Daughter went completely on her own for year 3 and she loved meeting her new flatmates.
Another advantage is if you really are not one for mixing, then a studio is another option. And all the ones ive mentioned at close to bus stops/bus station.
Disadvantages are that they can be pricier than university halls, and there might only be an option to do a 51week contract as opposed to the univeristy term of 40-45 weeks.
Another disadvantage is they might not be able to cater for single sex. Smaller properties I imagine not, but maybe the bigger ones might cater for that preference.
