Turnkey Apartment was a very disappointing experience. Even before we arrived in Prague the host was inconsistent in replying about his own offer of transportation and basic questions about the apartment, and did not reply at all until the evening before we left.
When we arrived to the apartment, we had received directions to pick up the key in a lockbox - when I opened the lockbox there was no key. I called the host who initially had no idea what was going on, and would call me back once he sorted it out. So my partner and I had to stand with all of our luggage on a freezing February night in the middle of Praque, without knowing wether we had a place to stay in or not. The host called me back and gave us an identical apartment available in the same building, so the problem was relatively quickly sorted out, but still a very stressful way to start a vacation. Besides all that, the mattress was so absurdly hard, it felt like titanium with a sheet. I cannot recommend Turnkey Apartments
