The apartment is very well located, close to the metro, to nice supermarkets, restaurants and bars. The building has an elevator, and is well maintained.
Everything works properly: the shower, the heater, the (tiny) kitchen... The bed is comfortable and also has good pillows. The place was perfectly clean!
The negative point is that the walls aren’t so isolated, so sometimes you can hear neighbors speaking loud (I woke up once at night with the noise). I had some ear plugs to help with that!
Another thing is that the bathroom is so small that while using the toilet you get against the tiny sink...
The place is perfect for one person in a short stay (in other words, I wouldn’t recommend it for long stays, it is tiny enough for a couple nights, for more than that you’ll be more well accommodated in a bigger space).
