The David's and Jackie's place was a great to stay in. Jackie was really communicative and helpful host, she bought us tram tickets, and saved us some time doing this.
The apartment is in very safe building that has plenty of locked doors with magnetic key. The garage is safe and easy to drive in and out. Considering quite high costs of public parkings, it saved us quite a bit of money.
The apartment was clean and comfortable. It has everything that's necessary. The wifi is fast (40Mbps - download) so Netflix works like a charm. The bed is good (though the pillow could be a bit bigger, but that's the personal preference) and rooms have a lot of space, so we felt quite cozy in there.
Our time spend in Praga was really great and staying in this apartment helped us to use our time to the fullest.
