We thoroughly enjoyed our stay at Alex's place. Our only complaints are really nothing that is within their control, i.e. walking up 3 very long flights of stairs in all the heat and humidity that was present in early July was brutal. The heat and humidity in the flat was higher than we would have liked, especially in the bedroom, but, again, that was not fault of Alex. There was an A/C unit blowing full blast the entire time.
We would absolutely stay there again, just maybe not in the heat of summer.
