I stayed with my parents and sister at Alex's place for a week and sadly it was not the greatest experience. The house location is perfect. If you don't mind walking you can go lots of tourist attracttions by walking. The house has enough space for 4 people but you cannot hang out in the living room all together as there is only one old sofa. We had to clean the place all over again as it was not so clean. We washed the towels and shower curtain, cleaned the floors and removed the dust. In our first day, we realised that the pipes were blocked in the bath. We immediately let Alex know and he and his wife tried to help. But it took 3 days to fix it and it was very frustrating as we couldn't take a shower. Other than that, there was no hair dryer but Ruth bring one when we let her know. There was no wifi but we knew that beforehand. All the cleaning materials supplied by them.
Overall, Alex and Ruth are nice people but the house clearly need improvements.
