What to say.... the place is amazing! Exactly as described, no surprises. The neighborhood is great although the taxi driver had a hard time finding it, but this might also have been because a road was closed that GPS wanted him to take. But Erol (Arthur's dad) was great and came to get us from where the taxi driver was stuck. Pretty sweet!
The AC in the apt was great because it was really hot when we visited Istanbul. I also liked the shower head with the perfect water pressure and temperature. Plenty of towels. Arthur also had a ton of Istanbul guides and maps available in several languages, which were helpful.
Arthur shared a ton of information upfront and was very responsive. He gave details about getting around and recommended eateries. We can personally recommend the Clock Cafe for Turkish breakfast (around the corner) and No 19 Dining with home cooked food and cooking workshops (next door). We also had an amazing experience at Antiochia Concept. The food was amazing and the owner presented my mom for her bday with a gift which was super nice.
In conclusion to the apt, all was well organized and clean. Arthur accommodated us with a last minute late check out request. I would definitely stay again. Very pleasant experience!
