Positives:
1) Great host, met us outside despite arriving after 10pm and lives a floor above so easy to get hold of (we didn't need to though).
2) The place is spacious and quiet, with great sound isolation with a nice selection of complimentary tea bags (the cinnamon one is tasty!).
3) Lovely bath and hot water allows it to get pretty steamy, also large and comfortable bed (except the pillow, which your head sinks straight into).
Small Negatives:
1) The thermostat seems a bit off, we set it to around 19c for comfort (any higher and the room is quite obviously higher than 24c and too hot to sleep in)
2) There is a creepy black figure of a person drawn on the wardrobe that gave us both a fright every time we saw it out the corner of our eye.
3) Slightly far from the center, around 1 hour walk to Charles Bridge and with public transport wait times around 25-30 minutes to the center realistically.
