I've stayed at this apartment for a week. I attended a summer school at the Technical Institute, and the location of the flat was just perfect for this purpose. Everything is very close, shops, cafes and restaurants, metro is almost at the entrance. The flat is small, but clean, and for one person is perfect, if you're not planning to cook. The only minor issues I could mention was noise from the elevator (situated next to the entrance door) and that it wasn't easy to adjust the warm water in the shower, it took some time. Otherwise, I liked the place a lot! And the hosts were replying very quickly, the check in and out went smoothly.
