I stayed at Sandra’s for six days with my bf. The flat is well located and has a concierge which is good as we always felt safe. We left our stuff at reception while we waited to check-in.
The flat is good value if you want somewhere well-located to see the city. It’s difficult to relax as there isn’t a sofa.
The only issue with the flat is that sound travels from other flats in the building. We were woken up by our loud neighbour several times.
Overall, would recommend!
