The flat is well located, and equipped correctly, even if it is small.
The check in and out were super easy thanks to clear instructions.
Few downsides, you can hear very well the noise from the street at night (just Friday night was very busy) and the curtains do no block light, so take a night mask and maybe earplugs if you want to sleep well.
Otherwise, the flat is quite well located, there's a cocktail bar, convenience stores and pizza places around the corner and the tram stop is a few meters away (although walking to the center is perfectly doable).
A great place for a few nights in Prague!
