I had a wonderful stay at this place. Its location was perfect, with a big mall and metro station nearby. The staff were so helpful, offering services such as car hire and tours/ticket assistance. The room amenities were excellent, including a soundproofed room, mini-bar, and electric kettle. The leisure facilities like the fitness centre were also impressive.

I would definitely recommend this hotel to anyone looking for a great place to stay.

Friendly and helpful staff, especially Vedat. Clean rooms with daily sheet changes. Good breakfast.

Felt extremely safe, no complaints.

The location of the hotel is perfect, being close to the metro station and a shopping mall. I have stayed here multiple times and the staff always remembers me, making me feel welcomed and valued. The hotel is clean and the room has natural sunlight, which is a plus for me. The breakfast offered is excellent with fresh fruits and vegetables. The front desk was helpful in assisting me with online check-in and providing an Istanbul card for transportation. I highly recommend staying at Avantgarde Hotel Sisli for a pleasant experience.

Over the New Year period, our stay at the hotel was quite pleasant. the staff provided complementary snacks and drinks, which was a nice touch. the hotel's location, right near a metro station and a major mall, made it easy to get around and access various amenities.

The open concept bathroom was not ideal as it lacked privacy. the cleaning service could have been more thorough.

We had an amazing stay at this hotel. The location is perfect, just a few steps away from the metro station and surrounded by shops and restaurants. It was so convenient to have everything within reach. The rooms were clean and tidy, and the staff was extremely helpful and friendly. The breakfast was delicious, with a wide variety of fruits and vegetables. The service was top-notch, and they even provided complimentary breakfast when I forgot to pay. The facilities were great, including a buffet restaurant nearby. We will definitely be coming back to this hotel again and again.

Convenient location near shopping mall and metro. Brand new property. Friendly and helpful staff. Clean premises. Fast and easy check-in. Comfy bed. Good WiFi for work. Option for in-room breakfast. Great price for value.

The location was great, beside the metro station. The staff was amazing and kind. Services were great, especially Mr. Furkhan who was kind and helpful. Rooms were clean and the cleaners were kind. Great hotel to stay. Staff were smiling and happy.

Nothing bad to say.
