We have stayed 6 nights at Taksim bomonti vip apartments and it was nice to spend time there. As location it is very central, just 3 minutes walk from metro station but we mainly walked to Taksim Square or at nights take a taxi, it is easier and cheaper as well.
Apartment is very nice and also useful decorated, we were 8 people totally and worried in the beginning if we could have comfort, however it was well enough. 6 people can sleep in the beds in bedrooms and in the living room there is a double sofa bed and also as we were 8 people we requested extra single bed, so it was even enough for 9 people.
Maybe if there would be breakfast service it would be even better, because i really dont like to prepare breakfast in the mornings, however my family always prefer to have breakfast in the home :(
Anyway, it was nice and staff was helpfull for touristic tips as well. I can recommend this unit for especially families and groups whom stay crowded.
