The apartment is excellent in practically every way except for one single drawback: it has no independent heating system when the weather gets cool as in autumn when we visited. There is heating for the entire building that is turned on when the building's tenants committee decides to, which is usually in winter. Apparently the average daytime temperature was not low enough when we were there to justify heating but the evenings and nights were pretty cold and we had no way of heating the apartment independently, which contributed to our coming down with the flu. Uchi later said that he could have given us a small heater but he did'nt when we asked for it.
This problem probably exists in many B.A buildings and should be taken into account by those who seek accomodation in intermediate seasons.
