Hello Hans, I just want to clarify the details you mention in your bad evaluation to our room.
First: when you make a reservation 2 hours before arriving, you should considerate that the host might be working at that time and could not be available at the time you want to arrive (most guests are considerate to that fact, and dont complain for waiting or make the reservation the day before).
I even offered to look for a way to let you in at the time you asked me, but you said there was good weather and wanted to visit the city around, at the end you came 30 minutes after the time i got home.
Second: The bathroon and kitchen were clean, and you are the first guest who complain about the quality of this matress.
Let me give you an advice for the future: when you have a request or complain about the room, the towels or the temperature of the room, please say something to the host, do not stay quiet and tell everything it's ok when is not, that is hypocrite and not fair to the host.
And our room is good, we know is not a 5 star hotel, but it goes according with the price. If you want the top quality, our suggestion is to stay at the best hotel in the city (€40-€60), not in a low price room (€17). It is not our fault you do not have the money to pay for a hotel with all the luxury you require.
