Very good stay overall.

For the reader's convenience, I will list the pros and cons of the facility.
Note that I'm an experienced traveler, and a host myself.
PROS:
* Extremelly well located: near Namesti Miru (the main square in Prague), main thoroughfares, public transportation, an abundance of restaurants, coffee shops etc nearby.
* safe, private parking available on the premises (for a small fee).
* pets are allowed.
* bathtub AND shower.
* breakfast buffet included.
* reception staff speak English (you'd be surprised...)
* staff are responsive and pleasant.
* rooms are nice and warm (I visited in the winter)
* daily room cleaning available.
* wifi.
CONS:
* kitchens are equipped with the bare minimum (no salt, oil or even dish detergent), so don't expect you'll be able to cook.
* there is a TV in the rooms, but it only gets 3 channels, including one in English (a news channel), and the signal is quite poor.
* rude guests smoke in the elevator (which is illegal) and on the passageways outside the rooms, which is utterly disgusting. I think there should be 'no-smoking' signs clearly posted throughout the property.
Conclusion: I had a pleasant stay overall, and I would definitely use that place again; I was stupid not to take advantage of the free breakfast more often, as I slept in, and I only had breakfast on the day of my departure. Live and learn!
