We had a wonderful 3-night family stay at MOOo Downtown in a one-bedroom apartment. The apartment was perfectly clean, very tastefully furnished, and equipped with all the household appliances a family could possibly need, which made our stay extremely comfortable.
The location was another major advantage — almost everywhere in Prague was within walking distance, making it very easy to explore the city with the family.
We did not try the breakfast, so we cannot comment on that, but overall our experience was excellent and we would happily stay here again.
