I booked this place last minute on a weekend and with a late check in. Regardless, everything went smooth, the administrator of the hotel was lovely and helpful all the way through, although didn't speak much English, he responded to all our requests, including a laundry service.
The amenities are somewhat outdated and may need a renovation but otherwise, it had all we needed for a two nights stay and matched the value.
Pleasant surprise was a huge local market which poped up in the morning. Definitely better than Grand Bazaar touristic experience. The market was so buzzing and authentic with low prices on veggies and fruits where Istanbul resident actually shop.
The extra feature of the hotel is a character terrace on the rooftop you can view the neighborhood from.
We loved staying in Beyoğlu and will stay there again, Taksim and Galata are in walkable distance, but Beyoğlu is just more real. Also, recommend Arter contemporary art museum with a cafe, small independent art gallery across, and Pera museum. All are within 10 min walk.
