Overall, it's a fine place with decent facilities. Suitable for a short-term stay (2 or 3 days maybe?).
The apartment is located in the city centre and it's about 15 minutes walk from the nearest metro station. However, there are about 500 metres of steep uphills leading to the apartment which is inaccessible for non-residential cars, making it inevitable for you to walk for 10 minutes uphills with potentially heavy luggage on arrival.
During my stay, there are a few issues with the facilities, like the air conditioner and the hot water. However, the host is really nice and will try to fix everything quickly. The bed sheet might need better cleaning, as I can feel that it's not smooth.
The apartment does not really have a private entry, according to my standard, as it only has one door, facing the street. Thus, I do feel it is too close to the street. The apartment might not be suitable for those who can be easily disturbed during sleep, since the noise from the street AND the upper floor (stomps can often be clearly heard) can EASILY penetrate the walls (you can clearly hear people talking). Also, the street light can go through the curtain so the room is not completely dark at night, which might be an unpleasant factor for some.
