We recommend paying a little more and choosing another accommodation due to the lack of hygiene. We requested a secondary cleaning on the very first day, which was done. "Cleaning" means cleaning the bathroom and vacuuming certain areas on the floor. One day later we had bed bugs (from the outside the rooms may look clean but there is so much dirt under the bed sheets or furniture and in the corners). With this report we got a new room 2 hours later, which was a "downgrade": view to the street, very noisy, dirty windows you can hardly see through. There we also ordered a second cleaning and let the cleaner clean the mattress for 10 minutes, as good as it could be saved. The kitchen is ok, the corridors have dust particles from "I don't know how long ago", windows can be opened a few finger widths (are secured, so no big air exchange possible). The staff is very friendly, but somehow no one is really responsible, so we didn't get a partial refund or gift of any kind as an apology for this unacceptable lack of hygiene.
