Jakub was very good with communicating with us, very promptly replying and assisting us to simple and quick check-in and check out. The place was bigger than I was expecting and located on the 2nd floor (no lift but if you don't have big luggage, it should be fine). The place was very clean and well prepared with nice furnitures. All amenities were ready and available. Around the house there was many nice cafes and bars to chill out if you do not feel going into too crowded central area.
Jakub was kind to store our luggage after check out and promptly answering us when we had trouble with the storage key.
I highly recommend his place for staying in Praha.
