this apartment is very big, and very well located next to restaurants, metro and sights.
there were a few problems -
only one toilet! we thought there were 3 by the description,but actually there is only one toilet and 2 showers.
the fridge is a mini fridge- barely enough room for a few drinks.
one room has access only through another room, so if you are not a close family - might be problematic, and it is definitely uncomfortable.
the elevator is very small- you can't go in with the suitcases, unless you practice yoga - the doors won't close (only one person with a suitcase fits).
The floor is made of very old parquet, so it makes a lot of noise: not only for us, but for the neighbours downstairs.
