Sorry to hear you believe we are less than stellar guests.
Just to clarify a few things:
1. We arrived late because we in fact did get lost- however as we are out of town international guests we do not carry an international cell phone which would mean getting in contact with you would be extremely expensive. Also seeing as we were underground for a good portion of an hour it meant we had no means of reception. We did ask you if you were waiting long, and you said only 20 minutes which is not "almost an hour later than agreed".
2. In terms of the hot water issue- yes, we should of let you know the status of the water. For your reference, the hot water was not better the next day. Again we were unsure of how to work the hot water boiler (again as we have different systems from where we are from). We should have contacted you again- but as I stated previously we had very limited access to internet.
3. Late check-out- we had previously clarified that we would be checking out later in the day and you were to let us know if this would be fine. Again as we are in a foreign country and with no access to internet we did let you know that it would be later than expected- once we able to secure internet access. I did check if it was OK and thought that everything was fine on that end
4. Saying that 2 plastic water bottles if "lack of respect for the property of others" is quite a bold statement.
