1. Emin was not answering to my question how to reach to apartment, although I've posed it 3 days before arrival (first time at Istanbul). Actually, he answered when we were at the airport when I was not able to read it. Not helpfull at all!
2. As a cosequence we had trouble finding the place - even taxi drivers in the neighbourhood area did not know where the apartment's street was. Also we had late check-in so we were searching at night time, on rain, running with our luggage on the unsafe Istanbul's streets full of unsafe drivers to be there at 2 A.M. when the last check-in was signed.

3. When we finally entered apartment, we were puzzled to see that nothing was like we saw on pictures (probably taken 10 years ago or in some other apartment). Dated, ruined and stained furniture; dated linen and pillows; useless chairs (with curved and uneven legs); bathroom shelf riuned with humidity. In one word we were disgusted to sleep, sit or eat in that place. Heating system made noise all the time.
4. Fridge was broken and made water puddle on the kitchen's floor next day. Emin was not happy to remove it (there was no cleaning lady available) and from that point he was insulted obviously thinking that this was not his duty.
5. Next night we had troubles with someone beating at the entrance doors, making noise, also someone was activating video interphone in the middle of the night and I contacted Emin about the issue. Again, he was not happy to come and see what happened, he finally said that "he didn't liked me" and was suggesting that the best way for us was to cancel the reservations??? One day before departure??? (spent there 4 nights)
We did not think of ourselves as demanding guests, we only wanted apartment presented at site's pictures - nice and clean.
Good sides of this story were Istanbul itself as beautiful city and one little, nice boy from local store that helped us with luggage during arrival.
