This apartment is close to everything and probably has the best local host in Prague.
Because our train arrived in Prague at 2PM, we contacted Peter to see if we can drop off our luggage first, but he allowed us an early check-in and welcomed us at the apartment with a cutely renovated and clean space and a dozen of local guide brochures, including recommendations for best beer, best coffee, designer places, etc. As a coffee believer, the "cafe guide" was the best I could ask for (Prague does have world-class coffee here!) . We stayed in Prague for 2 days, but found it not long enough for more discoveries.
Bathroom was clean and beds were comfortable enough for good sleeps. We would recommend any friends/couples/family traveling together to stay at this place!
