Once i stepped in the flat , I felt so home and The flat’s owner was so friendly and easy to communicate with . The flat is exactly as shown in the pictures , clean and tidy and nothing is missing to make your stay comfortable. There are alot of equipment and stuff that the owner supplied to use in the flat( coffee, tea, herbs and spices ) . Regarding building gym or swimming pool , I didn’t access yo them actually ad i have no time . The location is perfect and close to everything and for the transportation issue, there is a bus stop under the house that could take you to Eminonu and to the whole old city sight seeing and around 15 minutes walking to osman bey where you can take the Metro underground if you prefer so and 25 minutes walking to nişantaşi (popular street in istanbul) . The internet speed is good . The building is so close to a mosque and the sound could be loud to some but bearable , being a muslim , it was an advantage to remind me of the prayers time . I give this flat 5 stars rate for everything offered and it will be definitely my next choice when i come again to lovely city Istanbul . Thank you so much
