When we arrived we waited for 40min during the rain to get into the house. I did not get any message with code for the key box even though 2 days ealier I wrote message to Niko. We troed to call him with no result. At the end we decided to leave staying at another hotel but we found a lady working around that happened to know his friend and through her got in contact with Nico. Then he sent the code fast. Just the process was long and wet. Nico said he sent the message but I did not get it somehow. Otherwise the apartment - room with 2 single beds is worth its price. Small window is opening to the kitchen - be aware before you come in case you expect to have big privacy etc. Location is very good. 6min to Charles bridge by tram. It is very clean peaceful and quiet zone. Good to rest and for sightseeing. I recommend. Just make sure you have the codes before you arrive
