My wife and I had an excellent experience staying at Guner & Guven's residence. The unit was very clean, all features in working order and a secure residence. The neighbor hood is very close to İstiklâl Caddesi, about 8 min walk. Taksim square is a bit further , perhaps 15 min walk. I recommend one take a taxi from Taksim sq (if you arrived on the Havartas bus from the airport) as it is very difficult wheeling or carrying your luggage along the sidewalks from Taksim to this residence. Also, if you have heavy luggage and you are on a higher floor (we were on the 6th) it is difficult carrying up and down the stairs. There is no elevator in this building. But if your in shape it should not be a problem. The neighborhood might seem a bit "sketchy" but it is safe and the neighbors are friendly and helpful. Guner is really great in his correspondence and can provide you any info you need. Guven who resides in the building is very helpful and friendly, overall they are excellent hosts.
