All in all, it was a pleasant stay with Rico and his roommates.
They are all very nice, and you feel immediately welcomed in their flat.
Besides to that, the flat and the room is very charming and big.
1. For my custom it could have been a bit cleaner - my room - the table and chair were a bit unclean and I had the feeling, that the bedding was not freshly washed too.
2. The towels, which were promised in the offer, were very small and even unclean too. I think you shouldn't offer them at all, if you haven't a big fresh washed towel for showering for the guests. I was counting on that, and it felt disgusting to use them unwashed.
3. I lost more money than planned for the last night, because the water was turned off on the last day. There were constructions on the building, and they knew about it.
It was simply a failure and can happen to everyone.
But for me, it was very annoying, because I needed to switch to a hotel, where I needed to pay more.
