I had stayed at Sarova Shaba a year and a half ago, and my review was a 100% praise with no compromises.
This time, we still had a great experience although I feel some details pointed to the possibility (or need) of constant effort for improvement and excellence.
The shower head in our room was so clogged with limescale that the water jets pointed everywhere (mostly outside the bathtub) but towards the right place. This is not good for a five-star establishment.
When we checked in, the reception staff appeared to be overwhelmed and a little "out of breath". Admittedly, it was a long week-end with a public holiday, and at 100% hotel occupancy some bottleneck can be expected, but the staff on duty appeared to do nothing to avoid passing the sense of discomfort on to the guests they were attending to.
The variety of dishes available at the buffet felt a little less broad (or international) than during our previous visit, which made me wonder whether the chef had changed.
Anything else was, as for our previous stay, lovely and impeccable.
