I haven't seen a more dirty/unclean room for a long time and definitely never a 4th stars. We stayed 9 nights and I bet the room was never vacuumed the floor for dust or dirt. And this wasn't the worst part. The bathroom has such a bad smell that my girlfriend was close to puke several times. There was a cesspool like smell we couldn't get rid of. Even we placed the "yes" for cleaning service on the outside of the door many times, there was no difference, except for the new towels and cleaned mirror. We figured out that the smell was from the WC, more precise from the inner edge where water flows which looked like it was never cleaned or disinfected.
In a couple of days we found out that the bathroom was "refreshed" with our own perfume which was present in there.
We told at the reception about the smell and they said they'll send a plumber but we've seen no change.
In our before-last day in the evening when returned we discovered that our WC was way too dirty with some dark color stuff. We couldn't figure it out what it was as we didn't eve leave it like that. Yes, it was in one of the days with the "Yes" on the door.
We had breakfast included and in 9 mornings it was always almost the same, they barely change anything.
WiFi is almost unusable. Lucky us who had 3G on our phones.
The good side: big room, nice view to the lake, big balcony with terrace having a table and chairs. The nearest beach to the hotel is great.
