Generally a good stay, and a good spot for the price.
I did have to wear earplugs at night as you can hear the doors slamming and people above if you're in a small single room, as the bed is right by the hallway wall. Breakfast is minimal (small variety of fruit, scrambled egg, sausage, breads and cheeses) but enough for the morning. 10 minute walk to the metro and tram stop, very easy to access the main sights. I was worried about the AC after seeing other reviews (very warm in July!) but it was working great and quickly in my room. The room itself felt very modern, recently renovated and clean, which was a pleasant surprise compared to other hotels in this price range. I also felt safe in the area on my own at night, however some streets are not very well lit when walking back from the metro & tram stop.
Could benefit from a coffee machine at breakfast, and if you provided earplugs for guests. Breakfast pastries would also be great.
Prague is beautiful and I'll certainly be back!
