We spent 4 nights at the Galata Hotel and we had a great time. The hotel is around 120yrs. old and still has the charme of an old villa from back then.
The rooms are small but very nicely furnished. And the view from our room (4th floor) and terrace are amazing. You can see the Topkapi Palace, Gatata Tower, Bosporus, Mosques and a lot more.
The hotel is situated in a small street just off the main shopping and nightlife area of Istanbul. Perfect location! You can sleep in quite but you are in the middle of everything in just 1min walk.
Prices are moderate - compared what other hotels charge. And they give 5% discount if you pay in cash.
Breakfast is not amazing - but tasty. Fresh vegetables, fruit salad, cheese, yoghurt, börek and more. Every day the same though - so if you stay longer then a week you might wish for some changes.
The staff is friendliy and helpful - most of them speak poor English.
This hotel is definitly a recommendation. If we should go back to Istanbul we would stay there again.

Nightmare experience. Arrived stayed in room 305. Toilet, shower, hairdryer not working. Black bin bags covering shower walls. No ventilation, mosquitoes in room.Complained and received abuse from uncooperative hotel staff.
Would not stay at this hotel again. What good is a terrace view if service and standards so low.

Galata Antika Otel is ideally located in the hip Beyoglu/Taksim area. The hotel is currently under top-down renovation, and luckily enough we got one of the new rooms. The room was like a small Parisian suite, with high ceilings and beautiful detailing. The marble bath was magnificent but a little wonky, as it seemed the fixtures were not yet fully installed and the temperature in the shower was 'temperamental'.

The room was designer decorated, the air-conditioning was strong, and the breakfast was served on the rooftop with a view of the city and Bosphorous. The location was ideal: one block from the metro and the main street leading to Taksim square. We preferred the young local scene, rather than the tourist experience in Sultanemeht.

A lovely boutique hotel in an ideal location.

Stayed 2 nights, had no hot water and did not want to fix. Breakfast was not much
