We found Fehmi Bey at the Internet, as we were searching for a cheepish hotel in Sultan Ahmed with a good roof terrace. And we were not disapointed.
The hotel has a family feel to it. The staff in the reception were always helpful, and the room was kept clean and tidy. We stayed in the family appartement on the 1:st floor. No particular view, and rather boring with nothing on the walls. However, this was compensated by the spacious bed rooms and, in particular, the wast living room. Great for kids running around.
The location close to the ancient Hipodrome and the Blue Mosque is perfect, with spectacular views of the mosque, Haga Sofia, and the Bosphorus from the roof terrace. The terrace is a lovely place to spend a lot of time, reading or enjoying the hotel's excellent breakfast.

We were met at the airport by the good driver sent by the Hotel, and the service remained friendly and efficient all through our 3 night stay. Our room was small (as expected in this historical district), very clean and very well appointed. The view from our 3rd floor was great, and the A/C and beds were very comfortable. The hotel is 5 to 20 walking minutes away from the main sights you want to see in Istanbul, and the street car is a short walk away.
There was complementary bottled water in our room upon arrival (not so in other, more expensive hotels in Turkey) and complementary tea, etc. on the roof patio in the evenings. The included breakfast, also served on the roof-top, was very good: a good but not overdone variety of Turkish and other foods, and nice and fresh. The front desk will recommend places to eat - if you take the time to ask for the kind of dining you want, they'll give you a very good recommendation.
Liked best: location and ambiance. Can't think of anything that we didn't like!

It was 1st time for us to visit Istanbul and we stayed 3 nights at Fehmi Bey. Very nice location and most of sightseeing spots are within walking distance. Blue mosque, Hagia Sphia, Topkapi Place, Grand Bazaar, etc. We stayed standard room but I could see Blue mosque in front and it was very beautiful especially in the evening it gets illuminated. And the view from their roof terrace was just gourgious...
If you are morning person, you can take a quiet walk around Blue mosque area before it crowded by tourists.
Hotel staffs are always kind and nice. I would like to stay their hotel again for next visit.

We stayed for 4 nights in August at the Fehmi Bey Hotel and had a relaxing and comfortable stay. The hotel is in a great location, very close to the far end of the Hippodrome, so within easy walking distance of many sites such as the Blue Mosque and Agia Sofia. It's a fairly small hotel - about 30 or 40 rooms in total.

The room was fine - air conditioning, decent bathroom, small safe, comfortable bed, TV. We slept well and heard very little noise from the nearby streets. The bath had a shower attachment and sliding doors/screens and to have a shower you had to climb over the side of the rather high bath, which was a touch awkward.

Breakfast is served on the large rooftop terrace which has really fantastic views of the Bosphorus and the Blue Mosque. We spent a few hours on the terrace a couple of evenings as its a great place to admire the city and sights while enjoying a drink. Breakfast is a buffet with a choice of juices, breads, cheeses, fruit, tea/coffee, yoghurt etc.

There are a couple of PCs with internet in the lobby which are available for use by the guests which we found useful. The staff are friendly, and we were offered a taxi when we left for the coach station (I think the hotel normally offers taxis to the airport/coach station if you stay more than 3 nights). Our taxi ride was quite an experience, but we arrived in one piece!

All in all, a pleasant stay at this hotel which is well suited for tourists who want to be near the main sights.
