We really enjoyed our week's time stay at Alex's apartment. The apartment was clean and tidy and overall somewhat artistic vibe of the house added perfectly to the atmosphere of our stay.
Particularly, I'd like to note the location of the apartment - it couldn't be more perfect! Subway, tram station, bus station, great restaurants and local shops are nearby.
The only thing that was missing from the list of utilities promised was iron as it was damaged previously, hence, needed a replacement. However, this did not spoil our stay at all.
I hope to soon visit Berlin again and will definitely look to stay in this apartment.
