Location: The place is located at a sidestreet in the lively Galata/Tophane district. Always felt safe around there. Galata Tower and Tophane tram/bus stop both are less than 5 minutes away by walking. The next Metro (M2) stop is Sishane, which is located up the hill and can be reached in a little more than 5 minutes. Talking about hills: Keep in mind Istanbul is very hilly, walking up to Istiklal Street is steep but beautiful.
House: Individual check-in, no reception. There are washing facilities (washing machine, tumble dryer) in the basement. Nice for being independant at your accommodation.
Room: More spacious than it looks on the pictures! The bed is large and comfy, besides that you will find a wardrode and a small table. The kitchen was decently equipped and clean. Same applied for the bathroom. Warm water always worked fine. The large balcony is facing towards the bosphorus, and even offers a small view on the water.
Internet: WiFi always worked flawlessly for me. Both inside the room as well as on the balcony. It was always stable and fast enough for video conferencing.
Your host: George is a very nice and helpful with everything. Check-in and -out was super easy and flexible with him, and he offered help with various other things, such as getting a PCR test. Definitely recommended!
