We had a wonderful one week stay at Seyda's apartment. The apartment was very spacious with plenty of space for our family of four. It was well furnished with all necessary mod cons including AC in the living room, electric kettle and a washing machine. The wifi had a roughly 5Mb/sec download speed which is plenty for most use.

The neighborhood is a quiet residential area - there are a couple of local Efes shops nearby in case you need milk or basic groceries with a larger supermarket a short walk away. It's not really a touristy area at all, so brushing up on some Turkish phrases might be useful.

Osmanbey metro is a 5min walk away, as well as plenty of shops and restaurants. We spent most of our time touring the sights in the Sultanahmet area - to get there by public transport involves a metro to Taxim, funicular to Kabitas and then tram to Sultanahmet. If you don't have an Istanbulkart it can get quite expensive. We found that for a family of four getting a taxi was competitive price-wise with public transport, with fares varying from 15 to 25 lira, and trip time varying from 30-45min. The Besiktas ferry stop is also about a 30min walk away, which is convenient for visiting the Asian side of the city.

Seyda was a very pleasant and helpful host and I recommend her apartment to anyone visiting Istanbul!
