I stayed at Veronika's place with 2 girlfriends for 3 nights in March. We could not have asked for a better location - the Charles bridge is literally two blocks away, and in the other direction was the Astronomical Clock and plenty of really great restaurants and bars. We felt very safe in the apartment - it was located on the top floor of the building (with an elevator) and the surrounding streets were well lit. The apartment is perfect for a group - we each had our own room with 2 rooms to spare, and there are 2.5 bathrooms. The bathroom set up is a bit unique but worked well for us - one has a shower, toilet and double sinks, one has a toilet and small sink, and the third had a shower and sink. The common space is a bit small, but there is an enormous terrace that wraps around the 75% of the apartment with beautiful views. I highly recommend this apartment.
