Ideal for one or two travelers, comfortable, clean, great communication, and perfect location.
The space: It's basically one room with a private bathroom so it has a hotel feel. The space is really used well, it never felt small and actually it was quite spacious the way everything is laid out and organized. The ceilings are high so that helps as well. There is plenty of natural light from the street facing windows and the thick curtains effectively block out any streetlight at night. The shower was big enough and comfortable to use. The little kitchen is well equipped if you prefer to cook.
Beds: Very comfortable. We slept so well. For some people maybe it seems strange for a couple to sleep on technically two separate beds pushed together, but honestly you will get the best sleep because your partner's movements/blanket hogging won't bother you at all! The beds are fairly firm with nice big pillows and a comfortable duvet.
Cleanliness: Everything was sparkling clean, no dust or dirt.
Little things: Bathroom was stocked with basic things like cotton pads, hair dryer, shampoo, body wash, and plenty of toilet paper. I also really appreciated the fact that there was plenty of tea and coffee.
Location: You're right in the center of Prague near Wencesclas Square, but on a quieter street which is really nice since there was zero noise at night. It's about a ten minute walk to the river.
Host: David was an excellent host. There were never any communication issues, he was super responsive and seems to have a lot of experience hosting. We checked in and he made sure we were completely set and comfortable before leaving. The large wall map provided in the room was very clear and helpful.
Would definitely stay again!
