Lenka is a great host- very quick to respond to messages and is friendly, helpful and informative. Both check in and check out were very easy.
The apartment was clean and bigger than it looks in the photos- plenty of room for 2 people. The tram station is just outside and trams are very frequent. The journey into Old Town/Mala Strana takes around 25-30 mins.

I would definitely recommend Lenka's apartment to anyone visiting Prague.
