Very disappointing!
I've booked "Apartment Charlie" for a couple of my friends who traveled to Prague for a romantic trip, and decided on this apartment by the photos and description. Unfortunately, pictures can be very deceiving...
When I got there I realized that it looks like a place that only low budget students live in, and almost nothing was working :
1. The bed was wobbly and had the cheapest mattress you can find.
2. The secondary bed was broken, so we literally fell to the floor!
3. The Wi-Fi wasn't working properly and we had to stand outside the apartment to get a decent signal. I believe the modem is actually in a different flat...
4. The electric stove was broken (We didn't use it).
5. The dining chairs were wobbly and cheap.
6. The shower towels were old and unpleasant.
7. There was no sugar, dish soup, kitchen towels and so on...
Overall, this place was really not a place you look forward to come back to after a long day of traveling, and it seems that Evgeny put the absolute minimum effort into it.
Apartment Charlie has the potential to be very nice, but as of now, I would recommend you keep looking for something else.
