I had a great stay at Kosta's place. Love the stylish space, and the location was great, in a nice neighbourhood with plenty of foo options, short walking distance to the metro and most of the sightseeing places. Check in instructions were very clear and I had no problem accessing the unit. Kosta left a map of the neighbourhood which was very useful, and he kindly held my luggage for a few more days while I did a side trip.
