Great location but be warned in warmer temps!
I stayed here in July during the heat wave and initially I wasn't concerned because the owner listed the flat had air conditioning. I am from the US and I assumed it was central air or a wall unit because there was no other note or description on the listing. When I arrived, I discovered that the air conditioning was a plug-in room unit with no venting hose. When operating, the unit pumped out an equal amount of heat from the exhaust as the cool air from the fan. The temperature inside the apartment was very hot and humid except in the early morning when we could open the windows.
If you are staying in this flat during cooler months, the AC may not be an issue. We found that the unit had most of what we expected/needed. Small things we purchased included paper towels in the kitchen and face tissues but not a big deal. I would recommend this apartment for its central location and accessibility to the underground.
