You'll be more than happy to be staying in Sarah's cozy apartment, overlooking the Botanical Garden which is surrounded by the Munch Museum, the Natural History Museum, and the Botanical Museum.
Being an only 15-minute walk from the central bus and train station, Sarah's place is very accessible if you're arriving from / departing to the Airport, or any other major cities connected by rail.
Amenities are complete. You'll have no problem using the bathroom, laundry, kitchen, an of course Wi-Fi.
Sarah, her husband Oyvind, and their cat Hugo Boss are the most welcoming bunch. They (except Hugo?) are also very well travelled, so they understand the needs of fellow travellers.
