I had a very nice stay. Great residance with a lot of facilities which are great for relaxing after a long day of exploring the beautiful city of Istanbul. Also safety is guaranteed with 24/7 security, they are lovely people which are always in the mood for a quick chat and helpfull when needed. Had zero issues during my stay. Beds and bathrooms were clean and the whole residance was just splendid. Would really recommend staying here. Only little downside is that there is no public transportation very near, it's a 15 minute walk to Taksim metro station. But there are always taxi's closeby.
Would come here again if i'm coming back to Istanbul!
