Our stay was okay. The bed was comfy, the bathroom was pretty good, and there was a kettle that we could use to make tea or coffee. However, there were several issues with our stay as well:
1) Communication was poor. I sent at least three messages to the host not only to let them know when I would be arriving in Prague, that I had arrived in Prague, and that I was at the location provided. There was no response on Airbnb, no response on a third party app where I added the host's number, and they did not pick up. Since the host never provides a full address (the door number is missing even after the reservation is confirmed), I had to wait in the cold until someone finally picked up via said third party app, which was also not the host but a receptionist at the hotel the listing was apparently at;
2) There was no AC, although it was advertised as an amenity. The remote was simply not there. When I asked for it at the reception, I was told that the AC only worked during certain months out of the year, 'probably because of the environment'. I was not able to use the AC during my entire stay, and this information was not available on the listing description. I chose this place specifically because it had air conditioning;
3) The curtains are very thin and there are no blinds on the windows, and so when the sun starts to rise around 6am, a LOT of light seeps in. If you prefer sleeping with little to no light, make sure to bring some kind of sleeping mask to cover your eyes with, as even during the night a significant amount of light fills the room because of the streetlamps that are right outside;
4) The little hall between the bedroom and the door of our room, which is where the bathroom is located, often smelled like someone had been smoking right outside. This happened several times, and apparently to other guests as well, as I noticed the reception received multiple complaints;
5) The surroundings are noisy, especially due to cars honking and police/ambulance sirens, even during the night. Ear plugs are probably your best bet;
6) Someone - assuming from the staff - came into our bedroom on the second day of our stay while we were gone. Although it was nice that they tidied up for us, we had not provided any indication that we wanted them to come into our room, nor had we placed the sign on the door saying they could come in.
