The apartment is generally as advertised. I'll start with positives:
(1) Clean and spacious place as on the pictures
(2) Location is very central.
A few negatives:
(1) Level of noise - the description of the apartment states that it's not for light sleepers. We did not pay much attention to it as we are not light sleepers. However, the level of noise in the evening in the apartment is too much even if you do not have any issues with your sleep. There are a number of bars right downstairs (including a very big open air bar) and the music keeps blazing until 1-2 am. Afterwards, there were generally some shouting as well of the people cleaning the bars etc. We would find ourselves walking up a number of times through the night even though we did not have any trouble going to sleep as we were generally tired. If you have ANY sleep issues, then this place is definitely not for you.
(2) Once we left the apartment owner, Deniz (who was a very nice and responsive host) said that we damaged the lamp in one of the bedrooms. We did not. This is the first time something like this happened to us on airbnb. So general advice is to look around the apartment when you check in and report any damage to the host.
(3) It was 6 of us and we found that one bathroom (again as advertised so our own fault) is not very convenient for 6 people.
