Location is ok, the apartment itself is cozy and clean. Speaking of downsides: we had some minor problems with electricity (the teapot and upper lightning), but it's easily fixable. The ceilings in the bedroom are very low, do not recommend if you have problems with enclosed spaces. Internet speed is quite disappointing.
There is only one small window in the living room and ventilation basically doesn't exists.
The street outside your window is full of life so it's really noisy (and often smelly) from early morning till the late-late night. The AC is in place and working though, and window is pretty good, so with closed window it's ok.
It's a good place overall, if you don't mind sleeping with earplugs or enabled AC.
