Stayed at this apartment for two nights, Martin my host, always answered fast and was really nice,earlier check in and check out was not possible in this case which was absolutetly fine. First night it was too cold sometimes in the Apt even though the heater was set on sun and full heat but the biggest problem I had with this apartment is, that it is unbelieveable loud, you hear every single step outside, the elevator, every door that opens and closes and in my second night, the same floor neighbours had a party going on till 3am with a lot of people coming and going while also talking loud in front of the door, so no sleep at all till then. The elevator itself is not for claustrophobics. Still clean apartment with all the amenities you need. I didnt had that much a of pleasent stay there, but the the easy check in and the communication were really really nice.
