What's not in the pictures is a smell - the apartment is located on a low first floor, right above an open basement.
That's why it is very humid and smelly, especially in a "corridor" near the entrance. No direct sights of mold though.
First days it was really hard to get used to it. Humidifier helped, but not that much.
The second half of my stay when rains finally stopped and the weather improved it became much better.
The Internet is ok. It is stable and enough for having video calls, but is quite slow in general: 15-20 MBit download, under 1 MBit upload (ADSL).
Windows face a small inner garden. Neighbours have tables and chairs there, during sunny days it's nice to sit there.
But during rains it's an extra source of wet, and every evening - insects.
The location is good. Both nearest metro stations are about 10 minutes by walk.
Tram stops are about 5 min and the trams are very convenient in Prague. Run according to a schedule and can get you directly to the center, Malostranka or Vysehrad.
Large mall with hypermarket and ice arena: 10-15 min by walk.
The rest you can see in the photos and judge yourself.
Overall, if not the smell, I would say the apartment is a good value for money - for summer time when it is not that wet.
