Hello,
After few months of studying and living in Sweden, I think I am able to compare two cities I spend most of my time in – Uppsala and Stockholm – and share how I perceive these cities.
- Uppsala
Sometimes I would like to live in Uppsala to enjoy the proper student life 
since there is a lot of opportunities to go out and enjoy nice party with your friends. Another thing is that Uppsala is cosy and less chaotic city, so I feel calmer there but on the other hand, I come from Prague which is quite chaotic so maybe it would be too calm sometimes for me, in the end. I would say that Uppsala is more suitable for biking. You can find perfect cycling paths which are quite wide whereas in Stockholm, especially in the centre, paths are not really comfortable and sometimes there is a lack of parking for bikes. In Uppsala, everything is much closer and easily reachable. For example, if I need to go to IKEA, I choose the one in Uppsala because in Stockholm I have to travel quite far.
- Stockholm
What I really love about Stockholm are the parks and nature in the city. 
You can easily escape to the real forrest in the middle of the city as in Stockholm you can find large parks with very high trees, so you may really get a feeling that you are in the countryside. Moreover, there are the animals in the parks and you can often come across horses, sheeps, cows or rabbits in them – how cute. And as Stockholm is surrounded by water, it is really easy to find a place to relax with the view on water and just enjoy the moment. In Stockholm you can find many public events and things to do, therefore I suppose that social life could be more interesting (however, student life is still better in Uppsala). It is easier to travel from the capital city as more bus connections or trains depart from Stockholm central station. Arlanda airport has a strategic location between Stockholm and Uppsala and it takes even shorter time to get to airport from Uppsala. You have more places to discover in the city and it takes time until you feel that you have seen everything, which is pleasant for me to know that there are places to visit.
In a nutshell, both cities are beautiful and each of them has something to offer. I am really glad that I have an opportunity to discover both of them at the same time. I assume that I was in different situation as I moved to Sweden with my boyfriend who was going to study at Stockholm university and if I had moved here alone, I would not doubt and lived in Uppsala of course. So, if you are in similar situation as I was, and you have to decide which city will you live in, it depends on your subjective requirements. However, these highlights might help you to decide.
Enjoy your Sunday!
