Strongly recommended for travelers going to Istanbul. The hotel is a ten minute walk from Sultanahmet (Aya Sophia, Blue Mosque and Basilica Cistern). Another ten minutes walk from there and you'll be at the grand bazaar.
About the hosts, one of the two is always there for assistance even late at night. They'll both go out of their way to help you with anything that you may need.
The rooms are decent sized and with all the basic amenities. Heating and cooling are both up to the mark. There's a common area in the basement where you can enjoy complimentary drinks or just chat up with other guests or the hosts.
