Pros: the location of this flat is unbeatable. It took us 10-15 minutes on average to get to any place we wanted to by foot. Despite a very central location it was quiet in the evenings if we kept the windows shut.
For families with young children: you will need to use a steep staircase to enter the property with a heavy door - I would not be able to handle it with very light Yoyo buggy and a baby on my own. There is no bath, just two showers.
Greatest downside: the place was not properly cleaned on our arrival (rolled note on the floor under the bed, sticky handles, dust and dishes that needed a cycle in a dishwasher). Lynne was very helpful though and arrived to help with tiding up or when the socket did not work and I could not start the washing machine.
