Sara's place is excellently located in a great neighborhood with easy access to public transit, as well as great restaurants and bars. Walking distance to downtown and the tourist spots too. Its close enough to the nightlife if that's what your interested in, but also tucked just enough away in a quieter, residential area so you still relax after a long day out. Much like the city as a whole, its incredibly safe, even in the middle of the night.
The apartment is quite large, with plenty of room, so no need to worry about a tight squeeze if you have lots of bags. The kitchen is fully equipped if you intend to cook as well (living room has a coffee table and dining table for eating). The bathroom is quite large by Copenhagen standards, at least in comparison to other places I saw. I loved that the shower is rain shower, which was great after a tiring day to just be able to relax and let the water flow over you. There is a washer and dryer if needed. Bedroom is equipped with a Smart TV and the bed itself is fairly comfortable, though a touch on the softer side if you prefer your bed and pillows firmer. The space is "lived in", so closets and drawers are taken up by the host's belongings. Wasn't an issue for me as I traveled carry-on only and used the top of the dresser, but this may be a concern if you have lots of clothes. The apartment also has a balcony, which when the weather is nice, is a great place to sit out on and relax. The balcony has a small table and grill if you want to grill and eat outside.
Sara herself is very friendly and communicative.
All in all, Sara's place is great and in a prime location with good features. Highly recommend for the solo traveler or a couple.
