Esser's place was great and fit everything we needed. The neighborhood was very quiet (a little too quiet, as I felt like I was waking up the neighbors just from walking to the kitchen at early hours due to jet leg haha). So, sorry neighbors! ;)
We took uber most places and the costs were cheap - we did metro train a few times too, but with having luggage it was a bit far if you're carrying bags.
The balcony was adorable and the decor was super hip and cozy.
The only thing my Mom wanted me to add to this review is that it's not actually on the 3rd floor, it's really 4 flights of stairs. It didn't bother me, but she has walking problems so if you're traveling with someone with bad knees etc. this apartment may not be for you.
Overall it was a wonderful stay and we loved our trip to Denmark!
