I will start by saying the truth! The flat can host up to 5 people, as anyone can see through previous reviews in which there has been 4 or 5 adults and no one has complained, instead they gave 5 STARS for the flat. Yes, the flat is located in the basement of the building, but if you see in the listing/ad it is suitable only for children from 2 - 12 years old, not for babies as you confirmed above. This was enough for not have allowed you to stay in the flat, but as you were there and to avoid headaches for your family (arriving from a trip) I kindly allowed the baby (as you mentioned above), to stay. During all the time of your stay I was texting and asking if you needed something. I even provided 2 more hand towels you have asked and even allowed you to drop off your luggage before the check-in time - FOR FREE (things any hotel would do without additional cost). You never mentioned about hanger for coats or jackets (probably because there were) and even if there were not, if you have told, I could easily provide you more. The sofa bed is only one of the options given to sleep, as I've explained you upon your arrival, even saying the floor mattress would be more comfortable. "If the extra mattress wouldn't have been used" - It was and is there to be used, otherwise it wouldn't be provided. All the linens provided are for a standard size double bed, as there are no King or Queen beds, they surely fit the mattresses. Cleanliness for us is the most important, not only in the toilet/bathroom as in the rest of the flat. Unfortunately the flat was left dirty, with bottles of water and juice everywhere and the furniture out of its original places. This is really important and more than reasonable and expected that at least the furniture is in the same places it was before your arrival. The shower drain clogged was only mentioned in the last day - probably because it was not clogged before until you removed the protection from the drain, allowing hair to block it. From my point of view there was no good thing to mention, being this the main reason for only 1 star in your review.
