The appartment is just opposite of some storage of the Hilton Hotel. Which means it is loud there. On the first night we woke up at 2 in the morning as there where trucks loading and unloading. This was going on until 4 or 5 in the morning. It was a little bit better on the second and third night but still loud. On the forth night they were collecting the glass container at 3 in the morning which was very noisy.
Many have mentioned the noise in the comments already. All those comments are formulated very positively. It was worse during our stay. And we had the windows closed and we are not light sleepers.
We informed Iwona about the noise and she wrote, that she is very sorry but had not heard about the noise before. Which cannot be true, as there are comments about the noise in the profile.
We could not deposit our luggage before 11:30. Which should be mentioned in the description. It is only mentioned, that one can deposit the luggage.
We were informed, that we can checkin at 15:00 o'clock. When we arrived at 16:00 the cleaning was still going on but was finished at 16:30.
And the mattress are really bad, as others said in the comments.
All together, we would not stay there again.
