We stayed at Helena's apartment for three nights and we were very satisfied with everything. It is nicely furnished, with a comfortable double bed and a well-equipped kitchen. The living room is spacious, with a nice view on the trees of the park in front of the house.
Everything was very clean, like in a hotel.
Our visit took place in December and the outside temperature was very low, so the provided little electric heater was very useful. It was maybe not enough to make the whole apartment warm, but when we kept the wooden shutters closed then it made the temperature comfortable inside.
The location is excellent: it is just out of the way of the crowd but within a few minutes of walking of everything.
