Adela and her family are incredibly kind people. It was such a pleasure staying there for my week in Prague -- I only wish I had had more time to spend with them! Adela is so nice and joyful that it's contagious.
The room is great -- big with a big bed and desk and couch! I stayed there alone and it was tons of room for me. The location is ideal, as well -- in Letna, you're away from the tourist hustle and bustle but close enough to walk basically anywhere. If you don't feel like walking, there's a nearby tram that'll get you where you want to go super quickly.
Overall, loved my stay here and would recommend it without hesitation.
