Spent the weekend with my father. Great atmosphere and very very attentive service from the staff. We really felt like special guests. Breakfast is moderate. We had exactly the same for 3 mornings in a row. Should be better next time. But I will be back if I visit Istanbul! We had a very good time.

Very good hotel. Great lobby area, views. Excellent restaurants close at hand. Quiet even with a wedding party on premises. Helpful staff. Breakfast a bit ordinary. The room was excellent for comfort and cleanliness. We were a family vacationing with a four-year old. Pleasant walking right from the hotel. Left becomes pleasant after a little hike. But both are easy.

If you look at the lovely pic of the front of the hotel you can't fail to be impressed by the entrance, wide marble courtyard and sweeping steps up to the front door. The promise of excellent service and sumptuous rooms filled with antique furniture. This was going to be a wonderful start to our 25th anniversary trip.
WRONG! When we arrived the entire front courtyard was taken over by a wedding ceremony, there was no room service and we were asked to advise the front desk if we wanted to leave as the front entrance was out of bounds and we would have to be escorted out via the service door.
The room itself was quite large, but the bathroom was desperately in need of a refit with mouldy sealant around the bath, the whirl pool sockets were broken and didn't work and the toothbrush holder had been broken and badly glued. The sink hadn't been cleaned and still had toothpaste spits in it. The soap tray was caked in the previous persons soap.
The "antiques" were cheap reproductions, and the room was too dark as it only had 2 small lamps and no ceiling light. There were hardly any sockets, and only 2 clothes hangers in the closet. I called down for more and was told I'd have to wait until some guests checked out the following morning and they could be taken from other rooms.
There were 3 rooms overlooking the Bosphorus on our level and ours was on the right hand side, I noticed that it was possible to look directly into the room next door (the middle room) from our room, I realised this because I caught the person in that room staring into mine - he was a friendly chap as he even waved at me! Goodness knows how long he'd been there before I spotted him.
The first night we had to suffer constant noise from wedding guests running up and down the hall, but thought "oh well, we've still got another night"
Hmmmmm, guess what, there was a wedding the second night too! Unbelievable. Again we were unable to exit via the front and had to literally pick our way through the guests in the middle of the wedding ceremony. It was grossly unfair on everyone, us, the bride and groom and of course their guests who regarded us with open hostility. Again no room service. There was no drink making facility, or mini bar.
Breakfast was served on the lower level, it was a small room with low, oppressive ceilings. We were served by a waiter who didn't speak either English, French or German. So in the end we just used gestures. There was no choice, just a small plate with some bland cheese, a few slices of meat with curly edges and some olives. The second morning we asked for breakfast in our room but were told they were too busy clearing up after the wedding.
We were supposed to stay and third night but found that, yes you guessed it, there was due to be another private party that night! Enough was enough, we were paying 390eu/ night for a very stress filled stay so we voted with our feet and moved to the Four Seasons - absolutely luxury in comparison and for slightly less per night.
