We really enjoyed our stay. We were hosting our parents (60+ years old with mobility problems) and we have a 3 year old and everyone was comfortable and had fun. Here is a summary of the good things about this place:
Excellent location, clean house, helpful staff, accessible (no step entry, no steps in the street, bedroom and bathroom on the main floor), taxi stops in front of the building, clean swimming pool, 2 elevators, excellent communication, several convenient stores across the street and and next door. 2 restaurants across the street and next door. all restaurants and stores deliver to Elysium Residence.
two points to note:
some taxis take you to Elysium Hotel, but you should clarify you are going to Elysium Residence (show them the location on your phone).
It takes 9 minutes to walk to Taksim. If you go up the hill you will get to Comhiriyat street (has bus stop right at the corner if you want to go to anywhere else). The rest of the walk is flat surface. if you have a bad knee take a taxi right in front of the building and will be 25-30 TL (less than $2) to get to Taksim. There is Metro station at Taksim if you do not like to ride a bus.
Cihan is very responsive and helped us with airport transport.
