If you're looking for an apartment right in the middle of Prague's old town, you're absolutely right here. Location is perfect, all sights are in walking distance, you get a list of recommendations where to go, what to try and where you better stay away - for example where you might be treated as a cash cow - perfect.
The transfer you can order here is worth every cent - in my case it was nearly VIP feeling ...
The apartment itsself is perfect for one or two, the bed's comfortable, the other one maybe not that much - the second one is just a mattress on wooden floor - but I didn't really try it.
The communication with Alex and Kate was perfect, you can always ask questions and you'll get an answer quickly.
If you book here, better rely on the pictures than on the description. I expected something else when I read about a coffee maker. But the tesco nearby sells espresso cookers and there's a café right in the house, so it was alright. The apartment doesn't have a washing machine and no TV - as I was there for 3 days and don't speak czech, that was alright, too, but the description said both would be there. Everything else mentioned is there.
All in all. I had a very good time here and I'd surely come back.
