Vladimir,
We had a pleasant stay in Berlin and in your apartment:
The residence in which the apartment is located is really nice, architecturally interesting, in a "Mitte" district, central, ideal, to discover Berlin!
The apartment, 2 bedrooms, 2 bathrooms: very pleasant!
A little downside, however, the four of us had our breakfasts and dinners in the apartment:
the apartment is sorely lacking more dishes! (4 plates, 4 glasses,...)
When there are 4 of us, there is no "rotation" between the dishes in the dishwasher and our needs...
A container for water (a carafe, a glass bottle would also be appreciated (to drink, or put water in the fridge...)
Finally, for a stay of 1 week, a base of "basic products" would be appreciated (a little bit of coffee, tea, olive oil, pepper, balsamic vinegar, dishwasher pods, etc...) for the beginning of the stay (at least)
Certainly, we found salt, paprika, and curry!
It's still a matter of detail, but.....
So much we enjoyed our stay in Berlin, we took advantage of it... partly because of the localisation of the apartment in the city!
We will be happy to come back!
Thanks Vladimir!
