The place could be a lot cleaner and walking up four floors without an elevator is very tiring ,especially when you have a lot of bags to carry. The host was very rude because we accidentally took the key of the front door after checking in the first day ( I don't understand why there was only one key available in the lockbox, when you expect a lot of people to use it to get in. The next day he put two keys which I think it would be the right thing to do from the first place, before we checked in) . When we left the apartment on the last day, he wrote an angry message that we used a high temperature to the thermostat ( there were no specific instructions on how to use the heating) and that we took some linen and towels, which of course we didn't take. Also the flush of the toilet was not working properly, which was quite annoying, so we had to throw water by ourselves in the toilet.
