It was such a pleasure staying at Aurora's place! Aurora was spot-on with her communication, she was not around but was very helpful over WhatsApp in ensuring that I got to the place and inside safely and timeously. The place itself was very neat and tidy and really cosy, the kitchen was great (though no microwave but that's really not an issue), and I felt very at home :)
Would fully recommend you stay here if you're looking to explore Oslo, it is quite central to many things Oslo has to offer: Obos bike stop to get around easily, a lovely park nearby (that also has some awesome museums), and the bus and metro rail are quite close for transport to places further around.
One thing I would recommend to travellers is that if you have some big bags with you, make use of the trains, and use the metro rail to get as close as possible to the accommodation. Without the metro, and with big bags, it can be a slightly tiring uphill walk to the accommodation!
