Although I spent only a night in the apartment, I can say the following:
1. The check-in is flawless, all the information is well communicated and the host is extremely professional.
2. The apartment is spacious and well situated 5 minutes from the metro station (excellent connection).
3. Relatively clean, the building itself is somewhat old so don't expect miracles.
4. The second bedroom (on the roadside) gets quite noisy in the morning.
Would definitely recommend it for overnight stays or short stays. If you are planning a longer stay, make sure to bring coffee and a towel (or two) with you.
