We had a great week, and so did our 2 young children. The indoor space was big enough for a young family and there were useful touches such as sufficient washing up liquid, loo roll, clean towels, beach towels etc.
Although the flat is self contained and private, the building is typical of the area and the walls are quite thin - take ear plugs if you are a light sleeper. However; this didn’t wake our children at all.
There are useful tips left in a folder about bakeries, bars etc and we visited a few of them. The flat is about 5 mins walk (with a buggy) from the old town so good location which we appreciated.
