I can't say better things about my experience at Efi's place.
First, Efi responded immediately and the place was available on the same day of contact, which was unbelievable. Total life saver!
Second, Efi spent so much time cleaning up for us (even though the place looked spotless already!)
Third, the kitchen was wonderfully stocked, which was a bonus we were not expecting at all. Those touches are really appreciated and Efi took such good care of us.
As for the place itself, it's incredibly spacious and genuinely feels like a home with character and authentic feel.
The location is great, with easy access to some nice Czech eateries nearby and also being close to the metro and tram for access to the center (or it's very walkable as well). It's also nice and quiet.
I would not hesitate at all to stay again, I couldn't have had a better experience.
Also Žižkavárna cafe (just up the hill, <1 min away) was a great way to start the day!
