As per the title, this place is indeed in the 'best location'. Easy to get around Berlin as both train and tram options are less than 5min walk from the apartment. As are a number of food options. East side gallery (long section of the Berlin wall) also walking distance.
The apartment itself was adequately furnished with beautiful quirky touches and very clean. Super fast internet as well.
I booked last minute and Avi was able to accommodate me as well as maintain great/quick communication throughout. I'm looking forward to staying here again.
