We stayed at Ergin's place for about 10 days in Istanbul. The apartment exceeded our expectations. It was clean, well lit, and had all the basic necessities for a stay. Visiting from North America my family and I felt safe and comfortable here during our entire stay, and was tastefully decorated.
The location of the unit is very close to Taksim Square, Iskitlal street and other nearby attractions. Note that the apartment is on a way street so catching a cab was a little tricky, but a short 3 minute walk up the streets to the major streets would resolve that. The apartment is located on a bit of a hill, but much of Istanbul is like that.
When we arrived the security was able to greet us and show us to the apartment. The building manager is extremely nice and thoughtful. Although his English was limited we were able to ask for any help we needed.
Overall, the stay was Ergin's was a great one and if we were ever in the city again this would be a first choice!
