We stayed 4 nights at the Niles. The service is excellent, location good and rooms fair. It is a clean, simple hotel in a good location for touring. The restaurant options are limited in that area. The rooms are small and the beds are hard. The bathrooms seem to have been recently redone. The rooftop terrace restaurant is nice and the food excellent. I would recommend this hotel because of the kind and attentive service of the staff. Also, take a map and address with you if you need a taxi to take you to the hotel. NONE Of the taxi drivers could find the hotel.

Finding the Niles Hotel was a happy chance. Their sister hotel in the more touristic Sultan Ahmet region was full. We were not disappointed. Quite the reverse. We had an excellent stay.
Although difficulties at the airport delayed our arrival, we were met by our pre-arranged taxi (very reasonably priced). In half an hour we were being warmly welcomed by Seda - one of the most impressive receptionists I have had the pleasure to come across. Our room was simple, but it was comfortable, very clean with a more than adequate shower-room and a (free) safe. Although deep in the Istanbul rag-trade district, the street was very quiet at night. The aircon worked well and our four nights at the Niles were restful.
Upstairs, on the roof garden, the service was impeccable, with free tea, coffee and juice and swift service for other essentials, like beer. The fresh orange juice was . . . just perfect.
Breakfast was well organised and although busy, the food was plentiful and there always seemed to be a table. The view of the Sea of Marmara was a joy and the street scenes from this rooftop endlessly fascinating.
The hotel is usefully about 4 minutes from a tram stop. On the road with the trams, follow in the direction of Sultan Ahmet for about 100 metres and turn right down a pedestrianised shopping street. Here you will find the Sar restaurant. This is perfect for a quick salad lunch or more substantial kebabs. (Wine and beer served with a smile!) If you wish for shoes, handbags, leather jackets or briefcases, this is the area to shop. We found Santana to be excellent (1 minute from Niles Hotel).
Seda provided valuable guidance about how to get around and booked us into two excellent restaurants (Rami and also Hamdi Et Lokantasi) with brilliant views.
In its range, this is as good an hotel as I have stayed at. I cannot recommend it highly enough.

My girlfriend and I (well my girlfriend to be honest) found this fantastic hidden gem on Tripadvisor. We booked on the Hotel Niles website and arranged to be picked up at the airport. All went without a hitch. When we arrived it was quite late so we couldn't go out to eat, luckily the guy on reception said that they don't normally do room service but can prepare anything as long as it's a sandwich! Great! Seda the manager showed us a great route for our time in Istanbul. The hotel is so convenient for Hagia Sofia, Topkapi Palace and the Cisterns. All of which are within a 10 min walk of each other. The hotel to these sites are a casual 15 min stroll away. (right out of the hotel and then right at the main road and follow it down!) All in all I've not come across a more accomodating and generally friendly staff than at the Hotel Niles. Hotel was clean and well kept. Breakfast was included. Generally a fantastic stay. Would highly recommend to anyone looking for a good hotel close to Istanbul's top sights.

We stayed in the Hotel Niles for four nights. It is a small,very tidy hotel in a good location but can be a little hard to find. However the staff were outstanding, going out of their way to help - and without the additional charges so many other hotels apply. A lot of hotels could learn from them. We would definitely stay there again.
