We were welcomed warmly. We actually arrived in the midst of apartment renovation; Pecunia and Robert were transitioning, making two small accommodations out of the one we stayed in. They were very nice.
They indicated that some work had to be done immediately, and we agreed to let a handyman work in the apartment for 2 or 3 hours until his work was completed. However, the work was apparently not finished to their satisfaction and he continued to show up several times in the following days when we were not there; it was troubling that someone with whom we'd had no previous contact had access to our belongings in our absence. Moreover, we also noticed a camera in the one of the living areas which was always on, potentially letting someone know when we were there and when we weren't. We had a great deal of fun in Prague and ate several times at a restaurant recommended by our host. But you might have reservations until the renovations are complete.
