Finding an apartment in Magdeburg

We are considering 3 apartments right now, and We need your input.
Things to know: Warmmiete and kaltmiete. Warmmiete is the cost you will be paying each month to the owner. It includes water, gas, and heat. Kaltmiete is the price of the apartment without water, gas, and heat. The difference between the two is called the Nebenkosten. When one moves out, the total utilities used is calculated. If you've used less than the Utilities cost, you will receive some money back. If it's more, you will receive a bill for the missing amount. Electricity is not included in any listed rent costs (nor is internet, phone, tv or anything like that), but is generally estimated to be 20€ per average person. A Genossenschaft is, as far as we're concerned, a rental agency. When renting from them, one must pay a 1330€ deposit. One only receives this amount back after 2 years. Most apartments come without a kitchen sink, cabinets, oven, stove, fridge, or lighting fixtures. We estimate that buying those will cost about 250€. By law, renters must give 3 months notice before moving out.
The first is in Südenburg (Wolfenbuttelerstraße 31). It's 5 minutes by tram to the city center. It's in a neighborhood that is, itself, interesting. There's park just a block away that's not super big, but has things, like a place to climb on and pingpong table and benches and sand. The neighborhood has shops and cafes and restaurants. The apartment itself comes with a fridge, stove/oven, cabinets, sink, and lighting fixtures already included. It consists of a short entryway with the bathrrom just off that, then the kitchen, big enough to also be the dining room, and a bedroom. You see the problem with it... not a lot of space. It costs 300 warm, 200 kalt / month.
The second is in Leipziger Strasse (Lion-Feuchtwangerstrasse 6). It is large (living room, bathroom, kitchen, and 2 bedrooms), and has a balcony. It also has a good view of the city from the bedrooms, though kind of just an okay view from the balcony. Leipziger Strasse is about 10 minutes from the city center by tram. There is, however, nothing much in the immediately walkable area, maybe a restaurant or two. It costs 311.56€ warm and 198€ kalt / month. It is being rented out by a Genossenschaft.
The third is in Neu Olvenstedt (Hans-Gradestr. 107). It is large like the one in Leipziger Strasse, but the floors are an ugly linoleum. It has a BEAUTIFUL view from the balcony. The area has many small paths from apartment building to apartment building with statues, and small parks around each corner. It is 18 minutes from the city center by tram. it costs 184.16€ kalt, and 279.24€ warm. It is being rented out by a Genossenschaft.
